Structural Features
Metal Material: The LAY5-BS545's housing is typically constructed of metal, offering high strength and durability. It can withstand certain impacts and external forces, ensuring proper operation even in harsh environments.
Self-locking Function: Once the button is pressed, it automatically locks in place until reset by a dedicated operation. This effectively prevents the button from resetting due to accidental contact after an emergency stop, ensuring a safe stop.
Mounting Dimensions: The button typically has a 22mm mounting hole size, meeting the requirements of most industry-standard mounting holes, making it easy to install and replace on various devices and control boxes.

Working Principle
Circuit Disconnection: Under normal circumstances, the LAY5-BS545 emergency stop button's internal contacts are closed, ensuring the circuit is flowing smoothly and allowing the device to operate normally. When the button is pressed in an emergency, the internal contacts quickly open, disconnecting the device's control or power circuits and immediately stopping the device, thus preventing an accident from occurring or escalating.
Rotary Reset: After troubleshooting or resolving the emergency, the button needs to be rotated to reset the button. This recloses the internal contacts, restoring circuit continuity and allowing the device to resume normal operation.
