Abstract
A temperature regulator operating with a hydraulic expansion capsule or diastat (5) has a lever mechanism (30) for force transmission between the diastat and the switch spring (21) of a snap switch (20). For protecting the switch spring against overloading, into the lever mechanism is integrated a buffer or shock absorber, which is elastically flexible above a limit force associated with the operating force of the switch spring in the switching point and below the limit force is substantially rigid. The standard unit formed by the shock absorber and the lever mechanism is formed by a rocker (31) in the form of a sheet metal bent part, which has a L-shaped pivot lever portion (40), with which is constructed in one piece a stop-limited opening clip spring (41) pretensioned in the opening direction.
