Abstract: An actuation device for keeping the pushbutton switch activated and deactivated remotely. The actuation device includes a plunger which can be brought by external probing from a standby position, in which it does not switch the pushbutton switch, to an active position, in which it keeps the pushbutton switch actuated. The actuation device has a remotely controllable linear drive, a return spring and a return actuator and is designed in such a way that the plunger can be coupled to the return actuator by the remotely controllable linear drive, which is preferably driven by a Bowden cable, under tension of the return spring, wherein after deactivation of the linear drive, the plunger is pressed by the return spring into a position more remote from the pushbutton switch, thereby entraining the plunger into its standby position.

Abstract: Push buttons utilizing dome switches are often preloaded to take up any tolerances in the push button design causing a gap and provide consistent tactile feedback to a user. However, conventional push button preload techniques can be costly and difficult to consistently reproduce during push button manufacturing. A new pre-load design does not require pre-depression of the dome switch to close the gap, which permits a more forgiving tolerance to manufacturing variations.
