Types of Mechanical Interlocks
SIN Mechanical Interlock

  • ESH series – for use in moveable safety guard applications such as doors or covers on machinery or systems. This allows work to be carried out on machines only if the safety guard is closed, ensuring a safe working environment.

  • NZ1RS series – for safety guard or position encoder applications. These electrical mechanical interlock safety switches are positively driven auxiliary power switches and comply with the requirements of IEC 60947-5-1/EN 60947-5-1 annex K.

  • SIN series mechanical interlock for circuit breakers with an electromechanical latching device. These switches are ideal for use in a control system of machines to monitor the position of moving safety guards, and can be opened only if no hazardous conditions are present.
