SS-ISB4-SR Trapped Key Isolation Switch – Solenoid Release

IDEM’s SS-ISB4-SR is a trapped key operated control switch designed to turn off machine safety circuits.

The key is trapped when the main safety contacts are closed (machine able to run) and can only be released when the internal solenoid in the ISB4-SR is energised.

This then enables the key to be turned and released and the safety contacts opened. The key can then be used to release other devices in a trapped key system.

It can be used in conjunction with safety delay timers to allow a delay time before the solenoid is energised therefore allowing for any machine run down prior to releasing of the key.

Designed and manufactured in the UK the SS-ISB4-SR features a fully Stainless Steel 316 housing and barrel housing.

Versions with integral request button are available.
