The indication is provided by a reflecting signal surface (10), mounted behind a window in the push-button head on a frame support arms (9a, 9b). On the push-button depression the signal surface is located near the window, while on its release the surface moves away. In the push-button head is pivotally mounted a covering shutter, as in 2114526. The signal surface support has the two arms mounted on either side of the push-button plunger in the switch housing (6). At least one arm has a sprung hook (34), protruding through an aperture (35) in the switch frame (2). The hook latches behind this frame, supporting positively the arm from behind. The front of the arm has a limiting stop (9c) which abuts the switch frame. |
