<p>The present invention relates to a thermally-sensitive safety resistor comprising a heat-sensitive switch (7) formed by an insulating piece (1) provided with two bimetallic strips (3), a ceramic bushing (4) into which the heat-sensitive switch is inserted, and a resistance coil (5) wrapping around the bushing. The on-and-off of the switch (7) can be actuated by the heat produced by the resistance coil (5) when a current passes therethrough, thereby affecting on the switch to make or break the circuit.</p> |
