Cradle Position Switch

Three series of optional auxiliary switches are available for the cradle:

•

Cradle position switches (CE) to indicate the connected position.

•

Cradle position switches (CD) to indicate the disconnected position. This

position is indicated when the required clearance for isolation of the power

and auxiliary circuits is reached.

•

Cradle position switches (CT) to indicate the test position. In this position, the

power circuits are disconnected and the auxiliary circuits are connected.
