ABSTRACT:
An electric discharge lamp is disclosed utilizing an improved thermally responsive switch for operation of an auxiliary starting electrode. The improved switch has a more compact structural configuration which further accommodates temperature excursions beyond the design closure temperature without exceeding elastic limits of the metals employed in the switch construction. A metal halide lamp of relatively compact construction which employs the improved switch is also disclosed.
