An operation indicator is provided to indicate the open/closed status of device, e.g. a circuit interrupter operable between open and closed operating positions. The operation indicator includes two indicator members having cooperating interleaved or interlaced construction such that a relative small operating stroke of the operable device results in relatively larger open and closed symbol and indicating surfaces.
