Abstract
595,438. Automatic exchange switches. STANDARD TELEPHONES & CABLES, Ltd. May 30, 1945, No. 13546. Convention date, July 29, 1944. [Class 40 (iv)] [Also in Group XXXVII] A vibration-proof moving contact brush for a selector switch such as that described in Specification 563,501 to reduce microphonic noises in telephone circuits, comprises a pair of flat spring members 7 having contact surfaces at their lower ends, with flared leading and trailing edges to engage a series of stationary contact pins 13, and separated from outer spring members 6 by a block of resilient material 14 such as neoprene, supported by a lip 15 on the member 6. The contact springs 6, 7 are riveted to a fibre strip 4, which is secured by pins 2 to the moulded contact-carrier 1, and the upper ends of the springs 6 are formed with lateral extensions 11 to make wiping contact with the feeder-bar 12. Riveted to the ends of the strip 4 are supports 8 for a brush guide 9, having a narrowed portion receiving the contact springs and a flared groove receiving the contact-pins 13 to prevent transverse movement of the contact brush and hence short-circuiting two pins when in the position shown in Fig. 3B.
