Abstract
Abstract A push button switch having a spring biased slidably movable actuator is provided with a magnetically actuated reed switch of the sealed enclosure type. A permanent magnet is mounted in a cylindrical block rotatably mounted about its periphery in a cylindrical bearing in a fixed block adjacent the actuating slide. The magnet is rotated by a pin on the cylindrical block seated in a lateral slot in the slide. The switch is of a modular design and a plurality of the switches may be physically interlocked and mounted to constitute a keyboard assembly. The switch housings can accommodate integrated circuit components to incorporate features of a full circuit assembly.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
167 words
A push button switch comprising: a housing, a cylindrical rotor, and a support member therefor, means for removably positioning said support member in said housing, said member having a cylindrical bearing for receiving said rotor, a reed-type switch and means for mounting said switch adjacent said bearing, a permanent magnet carried by said rotor and having its poles in a line substantially parallel to a diameter thereof and adjacent said switch, a slide movable transversely of said bearing in a plane adjacent said support member, an eccentric pin on said rotor, said slide having a slot therein transverse to its direction of movement and positioned to receive said pin for rotating said rotor upon linear movement of said slide, a cover for said housing having an opening for access to said slide, means for biasing said slide toward said cover, and push button means aligned with said opening for moving said slide against the force of said biasing means to rotate said magnet for actuating said switch.
Claim 2
Dependent Claim
167 words
A push button switch comprising: a housing, a cylindrical rotor, and a support member therefor, means for removably positioning said support member in said housing, said member having a cylindrical bearing for receiving said rotor, a reed-type switch and means for mounting said switch adjacent said bearing, a permanent magnet carried by said rotor and having its poles in a line substantially parallel to a diameter thereof and adjacent said switch, a slide movable transversely of said bearing in a plane adjacent said support member, an eccentric pin on said rotor, said slide having a slot therein transverse to its direction of movement and positioned to receive said pin for rotating said rotor upon linear movement of said slide, a cover for said housing having an opening for access to said slide, means for biasing said slide toward said cover, and push button means aligned with said opening for moving said slide against the force of said biasing means to rotate said magnet for actuating said switch.
Claim 3
Dependent Claim
30 words
A push button switch as set forth in claim 1 wherein said support member comprises a block of nonmagnetic material, and said housing includes guides for positioning said block therein.
Claim 4
Dependent Claim
44 words
A push button switch as set forth in claim 2 wherein said block is of flat generally rectangular configuration and said guides position said block adjacent one inside wall of said housing and wherein said switch is positioned between said block and said wall.
Claim 5
Dependent Claim
35 words
A push button switch as set forth in claim 2 wherein said slide moves in a path substantially parallel to the inner face of said block and said switch is mounted diagonally of said block.
Claim 6
Dependent Claim
28 words
A push button switch as set forth in claim 2 wherein said block and said rotor are constructed of synthetic plastic materials having a low coefficient of friction.
Claim 7
Dependent Claim
41 words
A push button switch as set forth in claim 2 wherein said block is of rectangular configuration and has flat faces and including a slot formed in said block adjacent the inner wall of said housing for receiving said reed switch.
Claim 8
Dependent Claim
22 words
A push button switch as set forth in claim 6 wherein said slot extends diagonally of the rectangular face of said block.
