Eaton M22 Pushbutton Switch, 1NO+1NC, Flush Black Actuator, 16A, 22.5mm Mounting, IP66/67/69K Front 276293

Industrial control panels often need a reliable momentary pushbutton that can handle frequent operation and harsh environments. The Eaton M22 pushbutton switch provides a complete device with a flush black actuator and both normally open and normally closed contacts, rated for 16 A thermal current. Its 22.5 mm mounting diameter fits standard panel cut-outs, and the front protection of IP66, IP67 and IP69K ensures resistance to dust, water and high-pressure cleaning.

Who is it for

Panel builders, machine OEMs and maintenance technicians who require a robust, non-illuminated pushbutton for control circuits up to 500 V AC. It suits applications where momentary actuation and clear tactile feedback are essential.
