Abstract
672,011. Automatic exchange switches. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Dec. 13, 1950 [Dec. 16, 1949], No. 30435/50. Class 40 (iv). In a rotary switch, the contact bank 1 is fitted between two side plates 2 while the wiper carriage 9, which is rotatable about a shaft 6, is mounted between two other plates 3 together with its driving means so that when the switch is assembled each end of the shaft 6 is clamped between a plate 2 and a plate 3. The plates 2 carry a fixed arm 22 and a spring-urged rotatable arm 27 between which is held a stud 26 adjustably mounted on an arm 25 secured to the plates 3, the resultant force on the stud 26 being directed towards the shaft 6 so as to hold the two parts of the switch together. Resilient strips 19, 20 are secured to the shaft 6 and carry studs 21 which engage slots in the plates 3, allowing a limited movement of the shaft 6 relative to the plates 3. In a modification (not shown), the wiper carriages of a number of switches are selectively coupled to a common driving means.
