Abstract

833,226. Mechanical switches without quick action. GALL, D. C. March 7, 1957 [Feb. 6, 1956], No. 3684/56. Class 38 (5). The rotary switch disclosed in Specification 616,684 is located in any one of its various positions by a spring blade 27 which is rotated with the operating knob 20 and which engages the same contact stud 11 as the double leaf-spring brush 15. The blade 27 is fixed to the sleeve 21 carrying the brush 15 and the end 28 of the blade is formed with a substantially frustoconical projection which engages a conical depression in the contact stud. A number of switches and the appropriate banks of resistors may be mounted in a single box to form a decade resistor box (Fig. 3, not shown).
