9.2. Replacement of the switch of light of a backing


Work is carried out on a viewing ditch or the elevator.

We disconnect contacts from the switch.

Key "on 22" we unscrew the switch...

... also we remove it.

The new switch is installed as it should be, the return to removal. We cover contacts outside with an anticorrosive mixture, for example, by Movil or sealant.
We connect wires to conclusions of the switch in any order.
