The Flag Relay is constituted by an electromagnet which drives two changeover contacts and optical signalling at three positions with three colours which, in turn, drives two changeover contacts. The electromagnet, the contacts, the signalling mechanism and the card are enclosed in a plastic housing with front plate and plug- connectors. The front plate bears a window that allows the display of the three signals and includes a reset button mechanism. The relay is built in two versions: “energizing” (RCNE) and “de-energizing” (RCND). This relay is ideally suited for any environmental condition. A large number of flag relays can be assembled in banks.
