Interlock description

Our bolt locks are often used on rotary switches. Some operating procedures require switching of the electrical power to isolate a machine. After the power has been switched off the key can be released to take the next step, for example opening an access door.

The applications include critical installations like: industrial mixers, separators, dryers, granulators, cen-trifuges and also electrostatic precipitators. Dimensions and lock types depending on the size and type of the switch and client requirements.
