In an arrangement in which a plurality of relays have their contacts 16 ... 22 connected in series, an indicating system shows which of the contacts have not closed or which of the closed contacts have re-opened. The relay arrangement includes initiating contacts 24 which close to effect the energization of the various relay coils (not shown). An indicating circuit 28 (one shown) is associated with the contacts of each of the relays, the indicating circuits being connected between the conductors 12, 14 of an A.C. supply. When the relay contacts close, neon indicating lamps 56 are connected to the conductor 12 through the contacts and are lit, thereafter the voltages across resistors 62 are sufficient to maintain the lamps alight if any of the contacts re-open. When the contacts are closed, both sides of neon-indicating lamps 74 are connected to the supply conductor 12 and the lamps 74 are not lit. Should any of the contacts open, then the lamp 74 in the associated indicating circuit and those to the right of that circuit cease to be connected to the conductor 12 through the contacts and are lit, thereafter the voltages across resistors 80 are sufficient to maintain those lamps alight. A relay 26 with contacts 26A acts as "sealing" relay should the contacts 24 re-open and a relay 44 with contacts 44A only renders the circuits of the lamps 74 effective when all the relay contacts have closed.
