Abstract

In an electric switching device (1), particularly constructed as a temperature regulator, the resilient switching arm (14) controlled by a hydraulic expansion cell (12) for operating a snap switch (5) is fixed by means of positively engaging snap connections (32) to plate-like support parts (20) of a sheet metal support body (3) of a body (2), the support parts (20) on either side of the switching arm (14) being at right angles to joint axis (25) of arm (14) as lateral bends to a base plate (30) of support body (3) and receive between them an end portion of an insulator (4) carrying the switch (5). This leads to an extremely favourable taking up of forces, so that the support body (3) can be made from extremely thin sheet metal as a relatively elastic component. It also leads to a very simple assembly of the switching arm (14).
