Vacuum Switch
With a single-pole double-throw contact, these vacuum switches enable ON and OFF point control signals to be simultaneously received at the maximum or minimum operating pressure, while keeping the change in operating pressure very small.
Additionally, the entire vacuum side is made of SUS-304, and the welded air seal allows connection to high vacuum. Thus, these vacuum switches can also be used as protection for automated vacuum equipment and as a switch for safety circuits.
