Abstract

A mirror (8) is used in an electric distribution board, in order that an operator (9) can see the positions of the fixed and movable contacts (4, 5) of switches (1) in a chamber (7). The mirror may be of glass, polished metal, metallised plastic or of completely reflecting material. The operator is thus able to monitor the operation of the equipment visually but is prevented from touching the equipment, which is separated from him by a barrier (3).
