LAY5-BS142 Industrial 22mm Key-Release Emergency Stop Push Button Switch
The LAY5-BS142 is a heavy-duty, high-security emergency stop switch designed to safeguard industrial machinery and processing lines.Featuring a prominent, bright red 40mm mushroom head, this switch utilizes a secure Push-Lock, Key-Release safety mechanism.When pressed, the switch immediately locks into the open-circuit (OFF) position to stop operations and cannot be reset without the dedicated key, preventing unauthorized or accidental machinery restarts.
Engineered with a premium zinc alloy metal bezel base and high-strength, flame-retardant polymers, the LAY5-BS142 is built to thrive in harsh factory settings. It features pure silver alloy contacts that offer exceptional resistance to electrical arcing and erosion, ensuring a clean break every time. Designed for quick installation, it mounts seamlessly into industry-standard 22mm cutouts and connects directly to contactors, relays, and starter circuits.
