Abstract:
1. A circuit protector comprising: first and second terminals for electrically connecting to a circuit; a first member fixed to the first terminal and having a first portion that assumes a first shape in a normal condition and is convertible into a second shape in an overloading condition; and a second member having a first segment fixed to the second terminal by a securing element having a first melting point that is lower than melting point of the second member, and a second segment forming a second portion that is engageable with the first portion when the first portion is at the first shape and that is separable from the first portion when the first portion is at the second shape; and a pivot member having a recess for receiving and supporting the second member in a seesaw form with the first segment on one side for connecting to the second terminal and the second segment on the other side for the second portion to contact the first portion; wherein when an overloading occurs, temperature of the second member raises to the first melting point of the securing element, making the securing element molten and releasing the second member from the second terminal, which separates the second portion from the first portion.
