Abstract
Abstract One wall, such as the upper wall, of an elongated case of an adjustable electrical control device is provided with a slot extending lengthwise of the case. Disposed in the case lengthwise thereof is a pair of laterally spaced electrical elements engaged by electric contact means carried by a slide extending through the slot. A bar above the case extends lengthwise of it and is provided with longitudinally spaced recesses. The slide is moved along the case by an actuator connected to it, and either the slide or the actuator carries spring-pressed means normally projecting into one of the bar recesses, whereby the slide and actuator can be indexed along the bar.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
134 words
An adjustable electrical control device comprising an elongated case having an upper wall provided with a slot therethrough extending lengthwise of the case, electrical elements disposed in the case along opposite sides thereof, a slide member extending through said slot and movable lengthwise thereof, electric contact means carried by the slide between said elements in engagement therewith, a bar extending lengthwise of the case and provided with a plurality of longitudinally spaced recesses, supporting means rigidly secured to the case and bar holding the bar above said slot, an actuator member movable lengthwise of the bar and connected to the slide for moving the slide along the case, and spring-pressed means carried by one of said members and normally projecting into one of said recesses, whereby said members can be indexed along the bar.
Claim 2
Dependent Claim
134 words
