Rotary switch assembly with coupling means and rotatable conductive slip ring structure

Claim 1

A ROTARY SWITCH ASSEMBLY CONSISTING OF: A STATIONARY DISK OF INSULATING MATERIAL HAVING A NUMBER OF RADIALS OF CONDUCTING MATERIAL ON ONE SIDE THEREOF TO FUNCTION AS FIXED CONTACTS; BEARING MEANS MOUNTED IN THE CENTER OF SAID DISK; SHAFT MEANS EXTENDING THROUGH SAID BEARING MEANS SO THAT IT ROTATES WITH ITS AXIS PERPENDICULAR TO THE DISK; A ROTARY DISK OF NON-CONDUCTING MATERIAL SMALLER IN DIAMETER THAN SAID STATIONARY DISK ATTACHED TO SAID SHAFT MEANS; SAID ROTARY DISK ROTATING WITH THE SHAFT AND HAVING SLIP RINGS OF CONDUCTING MATERIAL PRINTED THEREUPON, AT LEAST ONE CONTRACT ARM ATTACHED TO SAID ROTARY DISK AND ELECTRICALLY CONNECTED TO THE SLIP RINGS; SAID CONTACT ARM CONTACTING AND SLIDING OVER SAID RADIALS ON THE STATIONARY DISK AND BREAKING WITH SAID RADIAL AFTER CONTACTING THE NEXT RADIAL; TWO FLAT RINGS OF INSULATING MATERIAL PLACED ONE ON TOP OF THE OTHER ON THE FLAT SURFACE OF THE STATIONARY DISK AT THE OUTER EDGE THEREOF; AND ELECTRICALLY CONDUCTING METAL STRIPS, PLACED AGAINST AND CONNECTING A DESIRED NUMBER OF SAID RADIAL CONTACTS AT THE OUTER EDGE OF THE STATIONARY DISKS, SAID TWO FLAT RINGS BEING CLAMPED AGAINST THE STATIONARY DISK AND THEREBY SECURING THE METAL STRIPS AGAINST THE FIXED CONTACTS.
