Economical and Reliable Thumbwheel Switch in Ultra-Small Size ■ Gold contacts are employed to provide maximum contact reliability ■ Printed circuit board employs epoxy paper as the base material, with gold plating over nickel plate for circuit pattern ■ Switch units can be assembled simply by fitting the integral hook coupler of each unit into the mating unit, thus eliminating the need of nuts and bolts for assembly
