Using a positive-operation snap-acting plunger, the contacts quickly and automatically disconnect to prevent accidents. This switch is a durable and long-lasting choice – it comes securely housed in a durable metal-alloy casing and has a mechanical lifespan of at least 10,000,000 cycles. The high IP66 (ingress protection) rating means it's sealed against dust and water jets, so it's suitable for use in harsh industrial environments.
