Abstract
An electric relay has a casing enclosing a thermally expandable mass associated with a thermistor (PTC) as a heat source, connected to an electric excitation circuit. A rod projects from said casing to come in contact with a rocker lever which, in conjunction with the reaction of a spring, causes a second spring to bend. The bending second spring moves an armature comprising a contact point, so that the contact point comes in contact with a second fixed contact point, thus closing an electric circuit. The elastic reaction of the springs and a tooth on the rocker lever bring the relay back to the resting position when power to the thermistor is interrupted.
