Abstract

An electric switch, and particularly a rocker switch, is proposed which is constructed as a monostable rocker switch. To achieve a resetting effect of the operating rocker (8) into the respective starting position, an elastic element (13) is provided between operating rocker (8) and switch housing (3), which becomes elastically deformed during the operation of the switch. After the load has been removed from the operating rocker (8), the elastic element (13) presses the operating rocker (8) back into its starting position.

Dependent claims

An electric switch comprising

(a) a switch housing having an inner wall face;
(b) a contact member movably supported in the switch housing and having first and second positions;
(c) a rocking operating member tiltably supported in said switch housing and having a position of rest and an actuated position;
the operating member further having
(1) a first part including a surface accessible exteriorly of said switch housing and being engageable for imparting an operating force thereon for moving said first part in a depressing direction;
and
(2) a second part formed as an elongated switching pin extending from said first part into said switch housing and being operatively connected with said contact member for moving said contact member upon tilting motion of said operating member;
said switching pin being movable in a compressing direction upon movement of said first part in said depressing direction;
said depressing direction being generally perpendicular to said compressing direction;
said switching pin having a side oriented towards said inner wall face;
a distance between said side of said switching pin and said wall face of said switch housing being reduced upon motion of said operating member from said position of rest toward said actuated position;
and
(d) an inherently elastically compressible element having opposite first and second surface portions and being disposed between said inner wall face and said side;
in said position of rest of said operating member, said first surface portion of said compressible element being in a face-to-face engagement with said side and said second surface portion of said compressible element being in a face-to-face engagement with said inner wall face of said switch housing;
in said actuated position said compressible element being compressed in said compressing direction and exerting a resilient force on the side of the switching pin urging said operating member into said position of rest.
