Elevator Emergency Stop Switch LW42B1-1824/OF 101: Premium Safety Core from Nanjing Zhuye Elevatorparts
In the complex ecosystem of elevator systems, the emergency stop switch is the most critical “last-line safety barrier,” designed to immediately cut off the elevator’s power supply and stop all operations in emergency situations such as overspeed, jamming, or passenger distress. A reliable emergency stop switch is mandatory for meeting elevator safety regulations and protecting lives and property. The Elevator Emergency Stop Switch LW42B1-1824/OF 101, exclusively supplied by Nanjing Zhuye Elevatorparts, is engineered to meet the rigorous safety demands of modern elevator applications. Designed with fail-safe logic and high durability, this switch complies with international standards such as IEC/EN 60947-5-1 and GB 14048.5, making it compatible with mainstream elevator brands including Schindler, OTIS, KONE, and domestic brands like Mitsubishi Elevator. Whether for new elevator installations or old elevator safety upgrades, it delivers instantaneous and reliable emergency shutdown performance that elevator operators and maintenance teams trust.
Nanjing Zhuye Elevatorparts has always adhered to a strict quality control system, and the LW42B1-1824/OF 101 elevator emergency stop switch is a testament to this commitment. Each unit undergoes comprehensive testing, including contact reliability measurement, insulation withstand voltage testing, mechanical durability trials, and emergency action response time testing. The switch features silver-nickel alloy contacts with high breaking capacity, ensuring stable and rapid circuit breaking even under rated current (10A) conditions, and minimizing arc flash hazards. Its flame-retardant engineering plastic shell meets V0 fire rating standards, providing effective protection against fire spread. With an IP65 protection rating, it can resist dust, water splashes, and vibration, adapting to various installation environments such as elevator cars, hall doors, and machine rooms. Equipped with a positive-locking mechanism, it can only be reset manually after activation, preventing accidental reset and ensuring safety.
Usage Guide for Elevator Emergency Stop Switch LW42B1-1824/OF 101
Proper installation, activation, and resetting are essential to ensure the reliable operation of the LW42B1-1824/OF 101 emergency stop switch. Nanjing Zhuye Elevatorparts strongly emphasizes that this switch is only for emergency use—misoperation may cause elevator malfunctions and endanger passenger safety. Installation and maintenance must be performed by certified elevator maintenance technicians to avoid safety hazards or equipment damage. Before installation, verify that the switch’s voltage rating (AC 220V/380V), current capacity (10A), and contact configuration match the elevator system’s specifications—refer to the product manual provided by Nanjing Zhuye Elevatorparts or consult our technical team for clarification.
1. Pre-Installation Preparation
Begin by cutting off the elevator’s main power supply and control system power, then lock the power switch and place a “Maintenance in Progress” warning sign at the machine room and elevator entrances to prevent accidental activation. Prepare essential tools: a screwdriver, wrench, multimeter, wire stripper, and anti-static gloves. Confirm the installation location (standard positions include inside the elevator car, outside the hall door, and in the machine room) and clean the area to remove dust, debris, and oil stains—contaminants may affect the switch’s locking mechanism. Inspect the LW42B1-1824/OF 101 switch for any external damage, loose terminals, or stuck buttons; do not use the product if any defects are found. Check that the switch’s reset key is intact and can be smoothly inserted and rotated.
2. Installation, Wiring & Activation Principle
Install the LW42B1-1824/OF 101 switch at the preset position, ensuring it is easily accessible and visible (the height from the ground should be 1.5-1.7m for convenient operation). Fix the switch securely with screws to avoid loosening due to vibration. Follow the wiring diagram from Nanjing Zhuye Elevatorparts strictly: connect the switch in series with the elevator’s emergency control circuit (note: it must not be connected in parallel to avoid failure to cut off power). The wire stripping length should be 8-10mm, and the terminals should be tightened to prevent poor contact. Use flame-retardant wires with a cross-sectional area of ≥1.5mm² to meet safety requirements. After wiring, use a multimeter to check the circuit continuity—ensure the switch is in the “normal” position (circuit closed) and the circuit is unobstructed. The switch’s activation principle is mechanical: pressing the red button immediately disconnects the circuit, and resetting requires inserting the dedicated key and rotating it clockwise to pop the button back.
3. Debugging, Daily Operation & Precautions
After completing installation and wiring, conduct a comprehensive debugging test: Restore the power supply, press the switch’s red button to check if the elevator immediately stops all operations and the emergency alarm is activated. Use a multimeter to confirm the circuit is disconnected. Reset the switch with the dedicated key and check if the elevator can resume normal operation after troubleshooting. During daily operation, clearly mark the switch’s position with “Emergency Stop” signs to ensure passengers and operators can find it quickly. Regularly inspect the switch (at least monthly) for button flexibility, terminal tightness, and shell integrity. Do not cover or block the switch—any obstruction may delay emergency response. Strictly prohibit using the emergency stop switch for non-emergency purposes (e.g., stopping the elevator to pick up passengers), as this violates safety regulations and accelerates switch wear.
Replacement Cycle of Elevator Emergency Stop Switch LW42B1-1824/OF 101
The replacement cycle of the LW42B1-1824/OF 101 elevator emergency stop switch depends on operating environment, activation frequency, and maintenance conditions. Under normal operating parameters—elevator runs 12-24 hours daily, the switch is rarely activated (≤5 times/year), and the installation environment is dry, clean, and free from severe vibration—Nanjing Zhuye Elevatorparts recommends a replacement cycle of 3-5 years. This timeline aligns with the elevator’s annual regular inspection cycles and is based on long-term field data, accounting for contact wear, mechanical component fatigue, and shell aging, which are key factors in ensuring the switch’s emergency response reliability.
For elevators in high-traffic or harsh environments (e.g., shopping malls, airports, or construction sites with heavy dust, high humidity, or frequent vibration), or elevators where the emergency stop switch is accidentally activated frequently (≥10 times/year), the replacement cycle should be shortened to 1.5-3 years. Harsh environments accelerate switch corrosion and terminal oxidation, while frequent activation wears the mechanical locking mechanism. For low-usage elevators (e.g., villa elevators, small office buildings with daily operation <8 hours) in stable environments, the cycle can be extended to 5-6 years, but semi-annual professional testing by Nanjing Zhuye’s technicians is mandatory to confirm contact performance, mechanical flexibility, and insulation resistance meet safety standards.
Immediately replace the LW42B1-1824/OF 101 emergency stop switch if any of the following issues occur, regardless of service life: The button cannot be pressed smoothly or fails to pop back after reset; Contacts are severely ablated or stuck, resulting in failure to disconnect the circuit; The switch’s shell is cracked, deformed, or the insulation performance deteriorates (insulation resistance <1MΩ); The switch fails annual safety testing or elevator regular inspection; The locking mechanism is damaged, leading to accidental activation or inability to reset; Frequent elevator emergency system malfunctions caused by the switch that cannot be resolved through maintenance. Timely replacement is critical, as a faulty emergency stop switch may fail to act in emergencies, resulting in serious safety accidents.
