Abstract
A detachable gas valve--switch assembly intended especially for a domestic gas range, in which the valve includes a body has a control element movable by a rotatable valve stem and the switch having a contact operating means rotatable by the stem. The switch is constructed and arranged for releasable retention in a position closely adjacent the front end of a gas valve. It is also apertured for mounting on the stem and for movement in one direction axially of the stem to said position and in the opposite direction for removal from said position. The switch and valve include axially extending resiliently engageable quick attach-detach coupling structure of novel construction for releasably and firmly retaining said switch axially in said position upon movement in one direction into said position, and includes also switch contact operating means engageable with said driving portion of said stem when in said position. Movement in the opposite direction disengages the switch retention and contact operating means. The coupling structure is novel in and of itself.
