Claim:
1. A surge suppression device with high structural stability, comprising a voltage sensitive element having a predetermined voltage rating, said voltage sensitive element increasing in temperature as voltage applied to the voltage sensitive element exceeds said voltage rating; a first terminal having one end electrically connected to a first surface of said voltage sensitive element; a second terminal comprising an arm portion and a contact portion, the contact portion being bent to the voltage sensitive element so as to be electrically connected to a second surface of the voltage sensitive element, and the second terminal being biased away from the voltage sensitive element; and a non-conductive barrier biased to move from a first position in which said non-conductive barrier allows electrical contact between the second terminal and the voltage sensitive element, to a second position in which the second terminal is not contacted to the voltage sensitive element and the non-conductive barrier is disposed between said second terminal and the voltage sensitive element, wherein said surge suppression device further comprises a blocking element and the second terminal further comprises an extension portion extended from the contact portion, and in the first position, a part of the blocking element is connected with the extension portion and another part of the blocking element is contacted to the non-conductive barrier, and wherein said another part of the blocking element has a notch for receiving at least a part of the non-conductive barrier.
