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.
