PROBLEM TO BE SOLVED: To solve problems that a response is delayed with a complicated structure although eliminating the danger of an over current in prior arts. SOLUTION: This bound type switch structure has a control structure including one alloy piece, one contact control part and one bounding part. A resilience part is installed to the contact control part 1 to engage to one terminal part. When the terminal part can be reciprocally moved transversely to the contact control part, the terminal part is contacted to an upper surface of a breaking part disposed at a switch body in normal state. When an over current flows into the alloy piece, the bounding part is overheated, deformed and pressed toward the terminal part, and the terminal part is downed from the upper portion of the breaking part by a resilient contraction, so that one end of the contact control part is lifted up to open a pressing of a resilient contacting piece. The resilient contacting piece is moved upwardly by its own elasticity. Two contacts are separated from each other and the power is rapidly switched to ensure a safety.
