ABSTRACT:
A voltage divider which can be manipulated so as to vary the output voltage thereof, prevents mechanical wear of the voltage divider element, provides continuous contact, and can be sealed so as to prevent interaction with the ambient atmosphere including first and second non-conductive substrates with a predetermined spaced portion therebetween. A first conductive strip on the second substrate is depressed across the spaced portion so as to contact at least one of a plurality of conductive taps on the first substrate, each of which are in contact with a voltage divider element so as to complete a desired circuit. By sliding while depressing the second substrate along its surface where the conductive strip is positioned, one or more successive taps are contacted so as to vary the voltage supplied to the circuit.
