Allen Bradley Guardmaster Safety Enabling Switch, 3 Positions, 2NC - 440J-N21TNPM-NP
Use this enabling switch from Rockwell Automation's Allen Bradley Guardmaster range to increase safety when accessing a hazardous area of a machine. It has three positions, meaning the circuit is cut when the trigger is either untouched or compressed too much. The circuit is only completed when the actuator is in the mid-position, and the operator is expected to either relax or tense their hand when an unexpected event occurs. This cuts the circuit and stops the machine.
