Part Number: TZ-7121
Roller Long Lever Limit Switch
its usable range of operating part is within one
third of the whole spring length from the front end of spring.
â– Enclosed Switches with Built-in Basic Switches for High Repeatability and
Durability of 10 Million Operations Minimum.
â– Â Suitable for applications demanding higher mechanical strength,
dustproof and drip-proof properties than those on basic switches.
