Abstract
A non-arcing electrical switch is disclosed wherein a solid-state switching element is operated in response to current flow within an external circuit. The switch is particularly suitable for use within an auxiliary lighting circuit of a gaseous discharge lamp. Because the switch operates in response to the current drawn by the gaseous discharge lamp rather than a specific sensed voltage, it may be used with virtually any type of clamp or lamp operating circuit.
