Limit switch TZ-8168, spring with metal rod

The CNTD TZ-8168 limit switch from the TZ-8 series is a robust industrial mechanical switch with a spring actuator terminated with a metal rod. This design is intended for applications where direct linear contact, high mechanical resistance and reliable switching even under repeated loads are required. Thanks to the metal rod, it is also suitable for rougher mechanical conditions and precise position detection.
