摘要：
A dual switch for a semi automatic welding gun has a switch lever that pivots between three positions. At the first position, the switch lever is disengaged from a first switch so that the welding gun is "off". In the second position, the switch lever engages the first switch to turn the gun "on". A locking lever retains the switch lever in its second position. Pivoting the switch lever to its third position releases the locking lever to enable the switch lever to return, under a spring bias, to its first position. A second switch is independent of the first switch and is selectively actuated to vary the welding schedule while the gun is either "on" or "off".
