It is equipped with a ø40mm mushroom-style operator and provides both pushlock and pull/turn reset functionality. This model includes one normally closed (NC) main contact and one normally open (NO) monitor contact, terminated via finger-safe (IP20) M3 screw terminals with an included cover. Featuring IDEC's 'Safe break action', the contacts are ensured to open even if the contact block is detached from the operator. This switch mounts into a standard ø22mm panel cutout and is ideal for industrial machinery, control panels, and automation systems requiring reliable emergency stop capability.
