Supports common contact configurations (SPST and SPDT), normally open or normally closed, suitable for switching loads in automation, signaling, and safety circuits. Provides rated current and voltage, contact resistance and dielectric strength specifications, and defined actuation threshold or temperature/pressure setpoints with hysteresis. Encased for environmental protection and lifecycle performance expressed in actuation cycles. Used for process sensing, control interlocks, and safety interlocks in industrial systems. ## Images - - - -
