The VS16K is a general purpose vacuum switch with a user adjustable set point and a small switching differential.The switch point can easily be set using a screwdriver over the range 30 - 1000 mbar. The IS16K vacuum interlock switch is designed to safeguard the operator by ensuring that electrical circuits in the vacuum chamber do not remain energised when the system is let up to atmosphere. Typical applications include interlocking of the HT cleaning or processing circuits on thin film deposition and vacuum systems.
