Embodiment Construction
[0028] In the key-type safety switch of the present invention, the switch housing has a key opening and a conductive element jack; the double alloy sheet is an electrical element that can be deformed and stretched when heated, and has high sensitivity to current. When the current is too large, the element will As the temperature rises, it expands and stretches, bends and jumps in the opposite direction, so as to achieve the purpose of cutting off the power supply. Another function of the double alloy sheet is to be in charge of connecting the conductive part and the driving part, acting as a bridge.
[0029] The conductive part includes a first conductive element, a second conductive element, a third conductive element, and an indicator light. One pin of the first conductive element is connected to the double alloy sheet to support the double alloy sheet, and the other pin extends to the outside of the switch housing. One pin of the second conductive element extends to the ou...
