The Edwards IS16K Vacuum Interlock Switch is designed for applications where the electrical circuits within the vacuum chamber must be de-energized when the vacuum system is let up to atmosphere. Typical applications would be the interlocking of H.T. and R.F. power supplies on vacuum coating systems. The interlocking switch consists of a positive break micro switch operated by a snap action diaphragm to ensure rapid separation of the micro switch contacts. The diaphragm is enclosed within the vacuum switch housing which is surrounded by atmospheric pressure and is coupled to the vacuum system by a KF16 NW16 flange.

The absolute switch point pressure will therefore vary by the same amount as the atmospheric pressure. A high current rating allows direct switching of loads without additional relays or external power supplies. The set-point is non-adjustable and cannot be tampered with. The IS16K is high vacuum compatible and corrosion resistant, with all wetted parts made from stainless steel.
