Abstract
A surge protector with first and second electrodes, with a heat sensitive member and with a contact member which is electrically connected with the first electrode and which is mounted so as to be brought into contact with the second electrode upon the temperature of the heat sensitive member reaching a predetermined value when receiving heat from the protector. In an embodiment, the heat-sensitive member is composed of a material whose shape is a function of its temperature, such as a shape memory alloy. The heat sensitive member can also serve as the contact member.
