A resistance element disposed on a copper laminated epoxy baseboard is electrically connected by a spring wiper to a collector formed by the copper plate on said baseboard. Resistance terminals integral with the baseboard extend out of the housing enclosing the assembly element. The wiper is actuated by a slider movable along the element to vary resistance. A marker on the slider indicates the wiper position relative to a scale imprinted on the housing.
