ABSTRACT:
An electrical switch including a fixed contact, a movable contact and means for moving the movable contact into and out of engagement with the fixed contact. A first legend indicative of one of the operative states of the switch is carried by a fixed part of the switch and a second legend indicative of the other operative state of the switch is carried by a part movable relative to the fixed part. The movable part is movable between a position wherein the first legend is revealed and the second legend is obscured and a position wherein the movable part obscures the first legend and the second legend is revealed. A resilient arrangement moves the movable part to one of the positions and there is provided a releasable latch arrangement for retaining the movable part in the other of the positions against the action of the resilient means. The switch incorporates a mechanism for releasing the latch at a predetermined point in the movement of the movable contact relative to the fixed contact and further includes a mechanism for returning the movable part against the action of said resilient means.
