Abstract

1372951 Secret contact-combination switches ELECTRONIC CONTROLS CORP 20 Oct 1971 [17 Feb 1971] 31298/72 Divided out of 1353216 Heading H1N A permutation switch comprises a plurality of coaxial, rotatable cylindrical tumblers T each of which has conductive 62 and insulating peripheral regions, a plurality of contact spring fingers 68, 76 resting on the tumbler peripheries, a tumbler control member 24, 32, 34, and means associated with the tumblers T whereby rotation of the control member 24, 32, 34 rotates the tumblers into positions wherein the conductive regions 62 are in contact with the contact fingers 68, 70 or the insulating regions are in circuit breaking contact with the contact fingers 68, 70, the contact fingers 68, 70 being mounted on circuit boards 86, 96 provided with conductive strips extending from at least some of said fingers 68, 70 to terminals and the tumblers T being at least partially surrounded by an insulating support 64, 66 formed to engage said circuit boards and hold said fingers in contact with the tumbler peripheries. The contact fingers 68, 70 project through windows 88 in insulating supports 64, 66, part of the boards 86, 96 being retained by slots 94 in the supports 64, 66. The supports 64, 66 and tumblers T are inserted into a cylindrical housing 12, 14 closed by a base plate 16 provided with slots 108 for the circuit boards 86, 96. The terminal portions of the circuit boards are secured by screws to the base plate 16.
