LAY5-BS542 Industrial 22mm Turn-to-Release Emergency Stop Push Button Switch
The LAY5-BS542 is an industrial-grade safety emergency stop switch engineered for absolute reliability in control circuit environments.This latching-action switch features a high-visibility, bright red 40mm mushroom head that triggers an instantaneous open-circuit (OFF) command when pressed.Utilizing a secure Push-Lock, Turn-to-Release framework, it locks mechanically into place to cut off power completely, requiring an intentional clockwise twist to reset and safely restore system power.
Built with a heavy-duty chromium-plated zinc alloy metal bezel and impact-resistant, flame-retardant polymers, the LAY5-BS542 is built to thrive in harsh, heavy-vibration factory environments. Internally, it features high-grade silver-alloy contacts designed to scrape themselves clean with each press, preventing carbon or dust build-up and ensuring zero-fail performance over a long service lifespan. It drops seamlessly into standard 22mm control panel panel cutouts and connects easily via secure hidden screw terminal clamps.
