Abstract

968,478. Retractive switches. STANDARD TELEPHONES & CABLES Ltd. Nov. 9, 1962 [Nov. 9, 1961], No. 42440/62. Heading H2B. In a push-button switch the armature 6<SP>1</SP> of an electromagnet 5 is arranged to engage a projection 3<SP>1</SP> on the button and thus to prevent its depression either when or until the magnet is energized (Figs. 2, 3, respectively). In the arrangement of Fig. 2 the armature may also serve to latch the button in its depressed position. When several such switches are mounted side by side provision is made for releasing one switch when an adjacent one is depressed consisting of a pivoted lever 15 (Fig. 1, not shown) engaging with the tip 6<SP>1</SP> of the armature 6.
