Abstract

1,062,228. Interlocking switches. BROOKHIRST IGRANIC Ltd. July 26, 1965 [Aug. 4, 1964], No. 31730/65. Heading H2B. [Also in' Division E2] Two or more push buttons 16, 18, are interlocked by a disc or discs 28 such that when. e.g., button 18 is depressed, to actuate a switch-operating member 14b, the button 16 is blocked from being depressed to actuate its switch-operating member 14a. Buttons 16, 18 are biased outwardly by springs 36 which bear at their other ends on a plate 38 retaining the springs 36 and the disc or discs 28 in position (Fig. 6, not shown).
