An electrical switch device has a casing with a viewing aperture therein, and switch actuating means is pivotally movable in the casing between an at-rest position and a switch actuating position. A toggle spring is movable with the switch actuating means for resiliently opposing its pivotal movement from both the at-rest and switch actuating positions. The toggle spring includes visual indicating means conjointly movable therewith for disposition in a viewable position at the viewing aperture in response to the pivotal movement of the switch actuating means from its at-rest position to its switch actuating position.
