A combined electrical switch and fluid control device, in which the switch comprises a casing having an insulating wall, a slider movable in the casing and carrying a contactor having first and second contact points, and first and second contact bars mounted on the insulating wall opposite the contactor, the first bar being engageable by the first contact point, the first and second bars having first and second segments projecting laterally therefrom for successive engagement by the second contact point, the first and second segments having a narrow gap therebetween of less width than the width of the second contact point, whereby such point wll ride between such segments without engaging the insulating wall to avoid burning of such wall and to avoid contamination of the second contact point by such wall.
