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 process
circuits on thin film deposition and vacuum systems.
The
IS16K 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.
