1 pole emergency disconnect switch for industrial trucks

Installation of emergency disconnect switches enhances safety at the work place significantly (meeting requirements for accident prevention). Single pole S134 switches are especially designed for DC applications.

Thanks to its snap mechanism the switch once actuated will complete the switch-off procedure in any case, because the snap mechanism works independently of the actuator. For ON and OFF there are two maintained positions.


  • Single pole emergency disconnect switch with snap mechanism
  • Magnetic blowout
  • Two definite maintained positions (ON/OFF)
  • Optional lockable version
  • Optional auxiliary contact
