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.
