Zusammenfassung:	A push button switch having a switch operation indicating means comprising a signal face arranged behind a window in the push button head. When the push button of the switch is depressed the signal face lies adjacent the window and when it is not depressed it is removed from it. The switch is provided with at least one covering shutter in the push button head and this shutter is arranged to pivot about an axis which is perpendicular to the axis of the switch. The covering shutter has a limb extending approximately perpendicularly from the shutter. The covering shutter is swung open by the signal surface carrying means on depressing the push button head. On the return of the push button head the limb is so swung from the rear side of the signal face carrier that the covering shutter is swung back over the signal surface.
