Abstract
939,279. Sets. G. KRONE. Dec. 6, 1961 [Dec. 14, 1960], No. 43658/61. Class 40 (4). In a telephone set the impulse transmitter is mounted on a chassis using resilient supports which also act as the electrical conductors between the transmitter and the other subset components. A mounting frame 3 is screwed to a printed circuit board 2 (Fig. 3) which is itself riveted to a base plate 1. Four helical springs 9 are located in respective chambers 7 (Fig. 1) the top ends of the springs projecting through slits in the top of the chambers so as to touch contact plates 11 of the transmitter and the bottom ends of the springs being riveted at 10 to the board 2. The transmitter is secured to the instrument at the front by a lip 13 on the transmitter which engages in a slot 12 of frame 3 (Figs. 1 and 4); and towards the rear by two blocks of resilient material 16 located in recesses 16a in a horizontal flange 17 of frame 3, lips 19 (Fig. 2) on the transmitter engaging recesses 18 in the blocks.
