The silver contact limit switch can increase the frequency of use of the conductor, increase the contact effect, and enhance the performance of the conductor. It also has the advantages of wear resistance, heat resistance and oxidation resistance.
Able to withstand some washdowns, shock and vibration
Easy-to-wire, smooth operation and reliable
The limit switch can be widely used in automatic control of various machinery, limit movement, transmission mechanism action or program control switch
