Embodiment Construction

[0035] In the following description, the terms "front" and "rear" are used with respect to a person's line of sight towards the illustrated elements. The front of the element means the side facing the human line of sight, and the rear of the element means the side facing the support to which the element is attached. Thus, when the electrical switch 100 is mounted on a component, the front means the side towards the inside of the component and the rear means the opposite side, ie the side towards the outside of the component.

[0036] The terms "inner" and "outer" are used with reference to the electrical switch 100 itself to denote, respectively, the side of the element towards the center of the electrical switch and the side of the element towards the exterior of the electrical switch.

[0037] Figures 1 to 3 A sealed electrical switch 100 according to the present invention is shown in . The electrical switch 100 can be of any type which is actuated externally by means of ...

Abstract

The invention relates to a cover for a sealed electrical switch, comprising a flexible sealing membrane (162) and a rigid front wall (140) comprising at least one window opening (160) in which a rigid sheet (165) extends and is intended to be displaced by the action of pressure applied thereto, the rigid sheet is connected to the edge of the window opening by a part (162A) of the flexible sealing membrane. According to the invention, the part of the flexible sealing membrane forms a corrugation (163) extending only between all edges of the rigid sheet and all edges of the window opening, such that the part of the flexible sealing membrane blocks only the free space left between the rigid sheet and the edges of the window opening in order to close the window opening.

Description

technical field [0001] The present invention relates generally to the field of electrical switches. [0002] More particularly, the present invention relates to a cover (decorative panel, panel) for a sealed electrical switch comprising a flexible sealing membrane and a rigid front wall including at least one window opening in which the rigid sheet Extends in the center and is intended to be displaced by the action of pressure applied to said rigid sheet connected to the edge of the window opening by a portion of a flexible sealing membrane. Background technique [0003] A sealed electrical switch generally includes a housing and a sealing cover that form an interior volume within which the device mechanism is positioned. The electrical switch includes a control of the device mechanism positioned outside the interior volume of the housing. The control unit actuates the device mechanism through the sealing cover. [0004] To ensure the tightness of the electrical switch, t...
