Abstract: In an electrical switchgear having a common housing for a thermostatic expansion material element and at least two electrical snap switches that can be actuated by a working piston of the expansion material element, the snap switches are electrically separated from one another and each have their own rocker for switching the snap switches in response to displacement of the working piston. The switching rockers move in parallel paths and are arranged to at least one side of the longitudinal center of the working piston.

Abstract: A temperature control apparatus, for example a hydraulic temperature regulator or thermal cut-out, comprises three interchangeably interconnected subassemblies, namely: a box-like sheet metal casing with an adjusting mechanism; an operating member comprising a hydraulic expansion box and a transmission lever with overload protection; and, a plurality of switch components to be inserted in holders on the casing. The switch components comprise a snap switch base and a snap switch operationally fitted therein, together with the corresponding flat connecting pieces.One or more of such snap switch subassemblies can be fitted to the casing, in order to provide a single-pole or multipole switch.
