Abstract 983,571. Cam-operated switches. GENERAL ELECTRIC CO. July 12, 1961 [July 14, 1960], No. 25224/61. Heading H2B. A multiple push-button switch similar to that of Specification 605,170 and having normally-closed contacts 70, 100 which may be opened by cam surfaces on sliders A... E which are movable, longitudinally by pushbuttons 62, also has one or more sets of normally open contacts 70, 111 which are similarly operable. Each button 62 actuates two pushrods, such as 42, having rounded ends 56 acting on sloping surfaces on the sliders.; A slider F has hook portions which retain any button in the depressed position against the bias of a return spring 66 until released by depression of a further button. A further slider G causes momentary actuation of one set of contacts during each depression of a button.
A MULTIPLE PUSHBUTTON SWITCH UNIT FOR CONTROLLING A PLURALITY OF CIRCUITS COMPRISING A PLURALITY OF MANUALLY DEPRESSIBLE ACTUATORS, A PREDETERMINED NUMBER OF LONGITUDINALLY MOVABLE SLIDERS ENGAGED AND OPERATED BY SAID ACTUATORS, THE SURFACES OF SAID SLIDERS ENGAGED BY SAID ACTUATORS BEING SLANTED BOTH FOR OPERATION BY SAID ACTUATORS AND FOR CONTROLLING THE POSITION OF SAID ACTUATORS RELATIVE TO EACH OTHER, A PLURALITY OF SWITCH ARMS BIASED IN ONE DIRECTION TOWARD A NORMAL POSITION AND BEING MOVABLE BY SAID SLIDERS AGAINST THEIR BIASING TO A SECOND POSITION, FIRST FIXED CONTACT MEANS ENGAGEABLE RESPECTIVELY BY SELECTED ONES OF SAID SWITCH ARMS WHEN SAID SWITCH ARMS ARE IN SAID NORMAL POSITION, THEREBY TO FORM A PLURALITY OF NORMALLY CLOSED SWITCHES, AND SECOND FIXED CONTACT MEANS ENGAGEABLE RESPECTIVELY BY AT LEAST ONE OTHER OF SAID SWITCH ARMS WHEN SAID OTHER ARM IS IN SAID SECOND
