The XW1E-BV422MFR is a physically operated, fireproofed emergency-stop switch manufactured by Idec. It is a standard type, rated at IEC/EN60947-5-1, and suitably sized for use with many industrial applications. This model features an actuating ring with a 22mm diameter flush red button, and is available in both momentary and maintained contact versions. It is designed to turn off electricity in the event of an emergency, and can efficiently control the power supply for any machine or equipment that uses electricity as its power source. When depressed, the contact breaks the circuit, thus stopping all operating motions and avoiding accidents. The XW1E-BV422MFR is durable, reliable, and designed to last through a minimum of one million operations.
