Edwards IS16K Vacuum Interlock Switch

Edwards IS16K Vacuum Interlock Switch

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.

Edwards IS16K Vacuum Interlock Switch

BOC Edwards' exclusive design provides the following safety features:
  • Single non-adjustable set-point, cannot be tampered with
  • Positive break switch, as required by BS4794/IEC 338-1
  • Rapid contact separation, prevents arcing
  • Breaks circuit directly, no relays required
  • Corrosion resistant materials exposed to vacuum
  • Direct pipeline mounting
