Isolation Switches

Isolation switches are used to ensure that an electrical current is completely de-energized for service or maintenance on the train. Craig & Derricott offer range of isolation switches which can be installed in a variation of applications.

These are 4-position rotary switches, fitted with a snap-action mechanism providing fast breaking and making between the contacts. Consequently, these units can be used both for direct and alternating current, even in circuits with high inductance. Numerous electrical combinations are possible, for simple applications (inverters or on-off switches) or for starting up complex motors.

The modular architecture of the basic components makes it possible to offer a wide range of variants, in the types of control and mounting. Compliant with standards EN 60 947-3
