Featured Product from steute

STEUTE's Series Ex ZS 80 emergency-stop pull-wire safety switches provide a means of initiating an E-Stop along the length, or around the perimeter, of a machine or process.  An E-Stop signal is generated by pulling the actuating cable at any point along its length (or by a wire breakage).  Reset by integral lever actuator pushbutton.
