Pull-wire switches with an emergency stop function are also available in the same compact design. ZQ215/ZQ315 pull-wire emergency stop switches have an unlocking function, which must be actively reset before the next actuation. The advantage of pull-wire switches over mushroom head emergency-stop push buttons is that the emergency-stop function can be triggered anywhere along the wire. With a wire length of up to 25 m available on the ZQ215/ZQ315 pull-wire emergency stop switches, they are capable of safeguarding even large danger areas.
Like position switches from Schmersal, this series is also modular in design, and all pull-wire switches can be individually configured and equipped with up to three switching contacts, various connection options as well as LED status indicators. The latter allow users to quickly see which device has been actuated and to reduce the often lengthy search for an actuated emergency stop, in turn reducing or even preventing unnecessary downtime.
