Elevator Brake Micro Switch RV-162-1C25/RV-163/RV-164/RV-165: Safety Detection Core from Nanjing Zhuye Elevatorparts
Elevator Brake Micro Switch, covering multiple models including RV-162-1C25, RV-163, RV-164, and RV-165, is a critical safety detection component for elevator brake systems. Tailored to match different elevator brake models and detection requirements, it is widely used to monitor the opening and closing state of the elevator brake—transmitting accurate “brake engaged” or “brake released” signals to the elevator controller. This ensures the elevator can only start when the brake is fully released and stops immediately when the brake is engaged unexpectedly, serving as a core safety guarantee for elevator traction system operation. Compatible with mainstream elevator brake systems (including Schindler, OTIS, and KONE), these multi-model micro switches are suitable for residential, commercial, and industrial elevators. Exclusively supplied by Nanjing Zhuye Elevatorparts, a professional provider of high-quality elevator electrical components, the Elevator Brake Micro Switch (RV-162-1C25/RV-163/RV-164/RV-165) fully complies with international elevator safety standards (EN 81-20, GB 7588) and electrical switch specifications. Manufactured with premium precision contacts and high-temperature resistant materials, it features excellent signal sensitivity, reliable switching performance, and strong anti-interference ability, winning trust from global elevator maintenance teams and manufacturers.
Nanjing Zhuye Elevatorparts adheres to the core philosophy of “Precise Detection, Safe Switching” and implements strict quality control for the multi-model elevator brake micro switch. Each unit undergoes multi-stage pre-delivery inspections, including contact resistance testing, switching sensitivity verification, high-temperature durability evaluation, and anti-vibration performance detection. The micro switch adopts advanced materials and technologies: the contact points are made of silver alloy, ensuring low contact resistance (≤ 50mΩ) and stable signal transmission for over 10 million switching times; the shell is made of high-temperature resistant PA66 plastic with IP40 protection rating, adapting to the working temperature range of -20℃ to 120℃ in the brake system; the actuator (plunger, roller lever) is designed with high-precision mechanical structure, ensuring accurate triggering with a small stroke (0.5–2mm); the wiring terminals are equipped with anti-loosening clamping structures, avoiding poor contact due to elevator vibration. The four models cover normally open (NO), normally closed (NC), and changeover contact types, enabling precise matching with different brake control circuits and simplifying selection for maintenance personnel.

1. Professional Selection & Pre-Installation Preparation
Installation must be performed by certified elevator electricians. Prior to selection, confirm the elevator’s brake model, contact type requirement (NO/NC), and actuator type (plunger/roller lever) to choose the matching micro switch model (e.g., RV-162-1C25 for standard plunger-type NC contacts; RV-163 for roller lever-type NO contacts). Consult Nanjing Zhuye Elevatorparts’ technical team if unsure about compatibility. Preparation steps: Cut off the elevator’s main power supply and secondary power supply, and lock the power switch; place a “Maintenance in Progress” warning sign at the elevator entrance and machine room door; open the brake system cover and disconnect the wiring of the old micro switch (take photos to record the wiring position); clean the micro switch mounting position to remove dust, oil stains, and debris; prepare professional tools such as a screwdriver, multimeter, and wire stripper.
SignalSignalFunctionFunctionFunctionFunction2. Correct Installation & Precision Adjustment
-
Switch Fixing: Take the matching-model micro switch from Nanjing Zhuye Elevatorparts, align it with the preset mounting holes on the brake bracket, and fix it with stainless steel screws (torque: 2–3N·m). Ensure the switch’s actuator is aligned with the brake’s trigger point—when the brake is engaged, the actuator is pressed (contacts switch state); when the brake is released, the actuator resets. Adjust the mounting position to ensure the trigger stroke meets the requirement (0.5–2mm).
-
Wiring Connection: According to the recorded wiring position and Nanjing Zhuye Elevatorparts’ wiring manual, connect the signal wires of the micro switch to the corresponding interfaces of the brake controller. Distinguish between signal lines and power lines, and confirm the contact type (NO/NC) to avoid wrong wiring (incorrect wiring will cause brake state detection failure). Tighten the wiring terminals firmly and use cable ties to organize the wire harness, avoiding contact with moving parts of the brake.
-
Signal Test: Restore the secondary power supply first, and use a multimeter to test the contact state: When the brake is engaged, the NC contacts should be closed (resistance ≤ 1Ω), and the NO contacts should be open (resistance ≥ 1MΩ); when the brake is released, the state should be reversed. Manually control the brake to engage and release several times to confirm the contact switching is sensitive and the signal transmission is stable. Adjust the switch position if there is a signal delay or failure.
3. Post-Installation Testing & Daily Maintenance
-
Comprehensive Function Testing: Restore the elevator’s main power supply and switch to inspection mode. Operate the elevator to run up and down, testing the micro switch function: Confirm the elevator controller receives the “brake released” signal only when the brake is fully released (elevator can start), and the “brake engaged” signal when the brake is engaged (elevator cannot start). Test the emergency brake function to ensure the switch can accurately transmit the brake state signal.
-
Daily Inspection: Maintenance personnel should check the micro switch during daily machine room patrols: Observe the switch shell for damage, deformation, or loose mounting screws; check the wiring terminals for looseness, oxidation, or disconnection; manually trigger the actuator to check if the switching action is smooth without jamming. Clean the switch surface and actuator with a dry cloth to remove dust and oil stains.
-
Regular Maintenance: Every 3 months, apply a small amount of contact cleaner to the contacts (if oxidation is found) to restore conductivity (avoid using oil-based lubricants). Every 6 months, recheck the wiring connections, trigger stroke, and contact switching sensitivity. For elevators in high-humidity, high-temperature, or dusty environments, shorten the maintenance interval to 1 month and enhance the switch’s dust-proof and anti-oxidation protection.
Recommended Replacement Cycle for Elevator Brake Micro Switch (RV-162-1C25/RV-163/RV-164/RV-165)
As a core detection component enduring long-term mechanical triggering, high-temperature baking (in the brake system), environmental erosion (humidity, dust, vibration), and contact wear, the elevator brake micro switch has a specified service life. Timely replacement is crucial to avoiding faults such as contact oxidation, poor contact, or switching failure—issues that may lead to incorrect brake state detection, causing the elevator to fail to start normally or lose the brake protection function, posing serious safety risks to passengers and equipment.
1. Standard Replacement Cycle
Under normal operating conditions (elevator daily operation time 12–24 hours, operating environment temperature -20℃ to 120℃, humidity 10%–95%), the recommended replacement cycle for the micro switch (regardless of RV-162-1C25/RV-163/RV-164/RV-165) is 2–3 years. This cycle is determined based on Nanjing Zhuye Elevatorparts’ long-term field operation data, contact wear tests, and electronic component aging evaluations. The cycle fully considers the high-frequency switching of the micro switch and the impact of the brake system environment on component performance.
2. Adjustments for Special Scenarios
-
High-Frequency Use & Harsh Environments: For elevators in high-traffic areas (e.g., large shopping malls, airports with frequent start-stop) or harsh environments (e.g., coastal areas with high salt spray, industrial sites with strong dust and high temperature), the replacement cycle is shortened to 1–1.5 years. High-frequency triggering accelerates contact wear, while harsh environments cause rapid oxidation of contacts and aging of the shell.
-
Low-Frequency Use & Stable Environments: For elevators with low usage frequency (e.g., villa elevators, small office buildings with daily operation time < 8 hours) and stable machine room environments (constant temperature and humidity, little dust), the replacement cycle can be extended to 3–4 years—only after Nanjing Zhuye Elevatorparts’ technicians inspect and confirm that the contact resistance, switching sensitivity, and insulation performance meet factory standards.
3. Immediate Replacement Conditions
elevator brake micro switchmodelReplace the Elevator Door Lock Contacts SEL2-A1Z immediately if any of the following issues occur, regardless of its service life:
-
The contact resistance exceeds 100mΩ, leading to poor signal transmission (manifested as the elevator failing to recognize the brake state or starting intermittently).
-
The contacts are severely oxidized, burned, or pitted (visible through inspection), causing intermittent signal loss or permanent contact failure.
-
The actuator is stuck or deformed, failing to trigger the contact switch normally when the brake is engaged/released.
-
The switch shell is severely damaged, cracked, or corroded, and the internal structure is exposed—losing the basic protection and switching function, and posing potential short-circuit hazards.
