Limit switch TZ-8166, spring with plastic rod

The CNTD TZ-8166 limit switch from the TZ-8 series is an industrial mechanical switch with a spring and a plastic rod, designed for precise detection of end positions, stops and linear movement. Thanks to the straight spring, it is ideal for applications with limited space, where high switching repeatability and reliable operation are required even under frequent mechanical stress.
