Abstract

In this push-button slide switch mechanism, an acutator bar pushes a plurality of spring-biased contact straps against permanently mounted contact terminals. Keybutton 11 is depressed causing key stem 13 to move in a downward direction from its rest position. Actuator bars 15 and 17, having apertures 19 cut in them, are mounted on stem 13. Contact straps 21 fit through apertures 19 so that, when the actuator bars 15 and 17 are moved downward, contact straps 21 move toward the right and abut terminal pegs 23 and 25. The latter can be selectively placed to vary the make point of the switch. Return spring 27 causes stem 13 to return to its initial position. Ball lockout mechanism 29 prevents the actuation of more than one key at a time. Key 31 is shown in its rest position.

Keybutton 11 is depressed causing key stem 13 to move in a downward direction from its rest position. Actuator bars 15 and 17, having apertures 19 cut in them, are mounted on stem 13. Contact straps 21 fit through apertures 19 so that, when the actuator bars 15 and 17 are moved downward, contact straps 21 move toward the right and abut terminal pegs 23 and 25. The latter can be selectively placed to vary the make point of the switch. Return spring 27 causes stem 13 to return to its initial position. Ball lockout mechanism 29 prevents the actuation of more than one key at a time. Key 31 is shown in its rest position. In this position, contact straps 33 rest against normally closed terminal pegs 35.
