ABSTRACT:
In a temperature limiter (1) with a rod-like temperature sensor (6), the outer tube is formed by a continuously tensile-stressed insulating tube (7) extending into a base (2). An inner rod (8), optionally articulated two or more times in the longitudinal direction, is constructed as a continuously pressure-loaded rod, characterized by temperature-dependent length expansion. The temperature limiter (1), e.g., for a glass ceramic unit, may have a circuit breaker (5) closer to the temperature sensor, and a more-remote signal switch (4). In that case, for operating the remote signal switch, a flat bar-like transfer member (9) traverses both switches through openings (54). The transfer member is coupled at the associated end and in adjustable manner with an operating member (30) for the signal switch (4), receiving the adjustment member (34). The parts are constantly held together in clearance-free manner by the tension of a restoring spring (40).
