Abstract
Clustered push button switches are provided in a casing having an insulating mounting plate with openings therein for guiding push button shafts which carry U-shaped spring contactors having respective first and second contactor arms. Front and rear sheet metal conductors are mounted on front and rear sides of the plate and are formed with front and rear contact tabs extending into the openings and successively engageable by the first contactor arms. The front contact tabs are bent rearwardly from the front sheet metal conductors. The rear contact tabs are bent forwardly from the rear sheet metal conductors. Additional sheet metal conductors are mounted on one side of the plate and are formed with elongated additional contact tabs extending into the openings for constant sliding engagement by the second conductor arms. The additional contact tabs are bent from the additional conductors in a substantially rectangular relation thereto. The front and rear contact tabs are spaced apart by insulating members on the plate to prevent bridging between the front and rear tabs by the first contactor arms.
