This is a solenoid-interlock safety switch from Euchner's TZ range, designed to prevent access to hazardous machine areas until motion has ceased. It combines guard locking with position monitoring, so the switch confirms the guard is closed and locked before permitting the associated machine function to run. Typical applications include interlocking on movable guards and doors within industrial machinery and automated production equipment.
