ASG LAY5-BS542 Emergency Stop Push Button (Mushroom Head, 40mm)
Secure your lift operations with the ASG LAY5-BS542 Emergency Stop Button. Features a 40mm red mushroom head, 1NC contact, IP65 metal body, and twist-to-release reset. CE and RoHS certified for elevator safety.
- High Visibility Design: Equipped with a 40mm Red Mushroom Head and a yellow protective guard to prevent accidental actuation while ensuring quick access during emergencies.
- Twist-to-Release Mechanism: Features a latching action that cuts the circuit immediately upon pressing; resetting requires a deliberate manual twist, preventing accidental system restarts.
- Robust Construction: Built with a durable metal body achieving an IP65 protection rating, ensuring resistance to dust, water, and harsh industrial environments.
- Standard Compatibility: Designed for a standard 22mm panel cutout, making it universally compatible with most elevator COPs (Car Operating Panels) and LOPs (Landing Operating Panels).
- Reliable Switching: Includes a 1NC (Normally Closed) contact block rated for high cycle life (1,000,000 mechanical operations), ensuring fail-safe performance.

Product Description
The ASG LAY5-BS542 serves as a vital “kill switch” in the safety chain of vertical transportation systems. Designed to meet the stringent requirements of EN ISO 13850, this emergency stop unit disconnects the control circuit immediately when the red mushroom head is depressed, bringing the elevator or machinery to a safe halt.
Professional Engineering: The unit is composed of two main parts: a robust operating head with a metal bezel and a contact block housing. The 1NC (Normally Closed) contact ensures that the circuit remains closed during normal operation and opens instantly upon actuation. The yellow protective guard (shroud) adds an extra layer of safety by minimizing the risk of inadvertent activation caused by bumping or leaning against the panel.
Durability and Application: With an electrical life of over 500,000 cycles under load and a mechanical life exceeding 1,000,000 operations, the LAY5-BS542 is built for longevity. Its wide operating voltage range (AC 220-400V) and high insulation resistance make it suitable not only for elevators but also for escalators, industrial conveyors, and CNC machinery requiring reliable emergency intervention.
Frequently Asked Questions (FAQs)
Q1: How do I reset the button after it has been pressed?
The LAY5-BS542 utilizes a “Twist-to-Release” mechanism. Once the red mushroom head is pushed in (locked), it must be manually rotated clockwise (indicated by arrows on the head) to release the lock and close the circuit again.
Q2: Is this button suitable for outdoor or dusty environments?
Yes. The unit features an IP65 protection rating, meaning it is dust-tight and protected against water jets from any direction, making it suitable for machine rooms and semi-outdoor panels.
Q3: Does the package include the contact block?
Yes, the standard assembly includes the operator head, the metal mounting base, and one 1NC (Normally Closed) contact block. Additional contact blocks can often be stacked if required.
Q4: What is the required hole size for installation?
The button is designed for industry-standard mounting. It requires a 22mm diameter hole in the control panel or mounting box and is secured from the rear with a tightening nut.
