ABSTRACT:
A switch assembly of the rotary and/or push-pull type is made up of a plurality of stacked switch section including rotary switch sections and/or push-pull switch sections, all actuated by a common central shaft. In the rotary sections, there are at least one pair of terminals, a rotary cam rotatable with the shaft, a substantially rigid cam follower contact arm biased against the rotary cam and movable, with rotation of the cam, between open and closed positions. The contact arm is hinged on and electrically connected with one of the pair of terminals. The other end of the contact arm has a dog-leg section and a resilient conductive leaf, favorably formed of beryllium-copper, on which a movable contact is mounted. The flexing of the leaf brings about wiping action of the movable contact when it closes onto a fixed contact connected with the other terminal. The push-pull switch sections have an axially movable carrier also including a flexible resilient leaf member on which movable contacts are mounted. The movable contacts of the push-pull switching sections also close with a wiping action on their mating fixed contacts.
