Thermoswitch
Temperature switches, temperature limiters or also thermal switches are used for the safe and multiple opening or closing of circuits. They usually consist of a bimetal, a spring washer, a plastic, Ceramic or metal housing and connection strands, wires or plugs. When the nominal switching temperature is reached, the bimetallic disc snaps into its Reverse situation. In the process, the contact system opens or closes and interrupts or thus contacts the electrical circuit. After reaching the temperature, the contact system automatically falls back to its normal operating Initial state back. Temperature switch with electrical latch must be disconnected from the power supply before resetting.
