VS16K Adjustable Vacuum Switch


The VS16K is a general purpose vacuum switch with a user adjustable set-point and small switching differential. This diaphragm operated vacuum switch is high vacuum compatible and corrosion resistant with all wetted parts made from stainless steel. A high current rating allows direct switching of loads without additional relays or external power supplies.

This switch should not be used for safety critical applications. For many interlock applications the Edwards IS16K may be more suitable.
