Abstract
Abstract A miniature switch designed for plug-in connection with printed circuit cards of standard integrated circuit systems comprises a shallow rectangular insulated case provided with a series of cantilever switch arms operable closed selectively by a common camshaft disposed at right angles to the direction of plug-in. The contact portions of the switch arms are oblique to their direction of actuation so that a rubbing contact is obtained as they are closed and opened. The switch arms extend from connector bodies which have projecting pins at one side of the case for plug-in connection with a terminal board, and have openings accessible from the other side of the case for receiving plug-in pins of any other circuit components of the system.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
117 words
A switch device for integrated circuit systems comprising a case having a shallow height dimension relative to its length dimension, a pair of switch members in opposite side portions of said case having cantilever arms with contact portions in overlapping relationship, said switch members having pin portions extending below said case for plug-in connection with a printed circuit board, a camshaft in said case lengthwise thereof having an accessible head at one end of the case permitting adjustment of the shaft to open and close said switch contacts, said case having openings through the top and said switch members having hollow portions accessible via said opening for plug-in connection of a circuit component with said switch members.
Claim 2
Dependent Claim
117 words
A switch device for integrated circuit systems comprising a case having a shallow height dimension relative to its length dimension, a pair of switch members in opposite side portions of said case having cantilever arms with contact portions in overlapping relationship, said switch members having pin portions extending below said case for plug-in connection with a printed circuit board, a camshaft in said case lengthwise thereof having an accessible head at one end of the case permitting adjustment of the shaft to open and close said switch contacts, said case having openings through the top and said switch members having hollow portions accessible via said opening for plug-in connection of a circuit component with said switch members.
Claim 3
Dependent Claim
108 words
A switch device comprising a shallow rectangular case of insulative material having a central cavity lengthwise thereof, a camshaft in said cavity journaled in the end walls of said case, switch members mounted in said case at opposite sides thereof, said switch members having contact arms extending into said cavity from opposite sides thereof with the contact portions of said arms in overlapping relationship and controllable by said cam shaft to open and close said contact arms, the contact portions of said arms being oblique to the direction of opening and closing movement whereby said contact arms are moved into and out of engagement with a rubbing action.
Claim 4
Dependent Claim
108 words
A switch device comprising a shallow rectangular case of insulative material having a central cavity lengthwise thereof, a camshaft in said cavity journaled in the end walls of said case, switch members mounted in said case at opposite sides thereof, said switch members having contact arms extending into said cavity from opposite sides thereof with the contact portions of said arms in overlapping relationship and controllable by said cam shaft to open and close said contact arms, the contact portions of said arms being oblique to the direction of opening and closing movement whereby said contact arms are moved into and out of engagement with a rubbing action.
Claim 5
Dependent Claim
201 words
A miniature switch device comprising a rectangular insulative case having a central cavity lengthwise thereof with bearing holes in the end walls and having a series of transverse holes through the case along its thickness dimension at each side of said cavity with narrow openings leading from each hole into said cavity, a shaft in said cavity journaled in said bearing holes, a series of cams mounted on said shaft, respective sets of switch members having body portions mounted in the holes at the opposite sides of said case, said switch members having arms extending through said openings into said cavity with the contact portions of the arms of one set movable respectively by said cams into and out of contact with the corresponding arms of the other set as said shaft is turned, said switch members having pinlike portions extending through the bottom of said case perpendicular to said shaft for plug-in connection with a printed circuit board, and said body portions of said switch members being hollow to receive pins via said holes from the top of said case whereby to enable a plug-in connection of circuit components from the top of said case with said respective contact arms.
Claim 6
Dependent Claim
201 words
A miniature switch device comprising a rectangular insulative case having a central cavity lengthwise thereof with bearing holes in the end walls and having a series of transverse holes through the case along its thickness dimension at each side of said cavity with narrow openings leading from each hole into said cavity, a shaft in said cavity journaled in said bearing holes, a series of cams mounted on said shaft, respective sets of switch members having body portions mounted in the holes at the opposite sides of said case, said switch members having arms extending through said openings into said cavity with the contact portions of the arms of one set movable respectively by said cams into and out of contact with the corresponding arms of the other set as said shaft is turned, said switch members having pinlike portions extending through the bottom of said case perpendicular to said shaft for plug-in connection with a printed circuit board, and said body portions of said switch members being hollow to receive pins via said holes from the top of said case whereby to enable a plug-in connection of circuit components from the top of said case with said respective contact arms.
