Abstract
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.
Claims4
An operation indicator comprising:
- a first indicator;
- and
- a second indicator disposed about said first indicator and including a plurality of portions for cooperation and interfitting with portions of the first indicator, said second indicator being movable from a first position to a second position so as to extend over predetermined portions of the first indicator whereby the first indicator indicates a first operable state with the second indicator in the first position and the second indicator indicates a second operable state with the second indicator in the second position.
An operation indicator for a device operable from closed to open status, the operation indicator including 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 via the relative movement between the two indicator members.
