LAY5-BS642 60mm Large Mushroom Head Emergency Stop Push Button Switch
The LAY5-BS642 is an industrial safety emergency stop switch featuring an oversized, high-visibility 60mm jumbo mushroom head. This switch utilizes a reliable Push-Lock, Turn-to-Release mechanical structure. When pressed, the switch immediately snaps into the locked, open-circuit (OFF) state, cutting power instantly to downstream machinery. It remains safely locked in place until it is intentionally rotated clockwise to release and reset.
Designed with a heavy-duty zinc alloy metal bezel base and impact-resistant, flame-retardant polymers, the LAY5-BS642 is built to endure punishing factory environments. The extra-large 60mm button surface is intentionally engineered for palm-strike activation or easy hit access in workspaces where operators wear thick safety gloves. It features premium silver alloy contacts that drastically minimize arc wear, ensuring long-term contact reliability.
