Limit switch TZ-8167, spring

The CNTD TZ-8167 limit switch from the TZ-8 series is a robust industrial mechanical switch with a spring actuator, designed for reliable detection of end positions, stops and linear movement. The spring design allows for smooth switching with sufficient stroke overlap, thereby protecting the switch mechanics and increasing its service life even in harsh operating conditions.
