<p>An electrical assembly (10) comprising a first electrical device (12) comprised of a non-linear resistant, temperature responsive element (14) and first and second electrodes (16, 18), the device (12) being connectable to a first power supply (20) such that a first electrical current (i1) travels through the resistive element (14) from the first electrode (16) to the second electrode (18). A second electrical circuit (24) is in electrical contact with the electrical device (12) such that the second circuit (24) may introduce a secondary electrical current (i2) into a localized portion of the non-linear resistant element (14), the second current (i2), when applied to the non-linear resistant element (14), causes the element (14) to change from a first resistant state to a second resistant state.</p> |
