Abstract

A surge absorber in which a thermal response switch is inserted in an input line at the input side of a surge absorbing element. The switch includes a conductive spring piece and a conductive hook piece. The base end of the conductive spring piece is fixed on either the first lead or the second leads and the tip of the conductive spring piece is provided with a pawl. The base end of the conductive hook piece is fixed on either the first lead or the second leads and the tip of the conductive hook piece is engaged with the pawl. At least one of the conductive spring piece and the conductive hook piece is made of a thermal response piece. Upon stopping of the applied continuous overvoltages or overcurrents, the switch can automatically be restored depending on an extent of the overcurrent by a manual operation.
