Abstract
Abstract A rotary switch having a plurality of outputs energized according to a prearranged pattern during rotation of a shaft of the switch includes first and second switch boards spaced apart and having respective contact portions formed on the facing surfaces thereof. The contact portions of the first board include an arcuate collector and a plurality of fixed contacts arranged in a predetermined pattern, and the second board includes a plurality of fixed contacts arranged in a predetermined pattern. A slider is held rotatively between the switch boards and has two pairs of electrically-connected conductive arms with a respective pair of conductive arms extending towards the contact portions of each board. In this way, each of the fixed contacts can be connected electrically with the arcuate collector in a predetermined pattern as the slider is rotated.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
114 words
A rotary switch comprising: a first switch board having a semicircular common contact and a fixed contact having a plurality of contact points, a second switch board having two fixed contacts having a plurality of fixed contact points, a slider support means including two sliders connected electrically together and each slider having at least one pair of contactors so that one of said pairs of contactors formed on one of said sliders is brought into contact with said common contact and said fixed contacts formed on said first switch board while a pair of contactors formed on the other slider are brought into contact with said fixed contact formed on said second switch board.
Claim 2
Dependent Claim
114 words
A rotary switch comprising: a first switch board having a semicircular common contact and a fixed contact having a plurality of contact points, a second switch board having two fixed contacts having a plurality of fixed contact points, a slider support means including two sliders connected electrically together and each slider having at least one pair of contactors so that one of said pairs of contactors formed on one of said sliders is brought into contact with said common contact and said fixed contacts formed on said first switch board while a pair of contactors formed on the other slider are brought into contact with said fixed contact formed on said second switch board.
Claim 3
Dependent Claim
136 words
A rotary switch having a plurality of outputs energized according to a prearranged pattern during rotation of a shaft of said switch, said switch including first and second switch boards spaced apart and having respective contact portions formed on the facing surfaces thereof, the contact portions of said first board including an arcuate collector and a plurality of fixed contacts arranged in a predetermined pattern and said second board including a plurality of fixed contacts arranged in a predetermined pattern, and means including a slider held rotatably between said switch boards and having two pairs of electrically-connected conductive arms with a respective pair of conductive arms extending towards the contact portions of each said board for connecting each of said fixed contacts electrically with said arcuate collector in a predetermined pattern as said slider is rotated.
