Integral multiswitch display panel
First Claim
1. A manually-operated integral multiswitch control and display panel comprising:
- an open top housing;
a multiswitch panel closing the top of said housing and having a plurality of openings therein;
a plurality of pushbutton switches, each having an insulating base within said housing and a pushbutton extending up through one of said openings;
a control circuitry printed circuit board within said housing common to said switches and having a plurality of holes therein, one for each of said switches;
each said switch having stationary and movable contact means mounted on the rim of the associated hole and connected to the printed circuit on said board and actuator means within said base comprising an actuating member extending from the associated pushbutton down through said hole for closing and opening said contact means when said pushbutton is actuated;
an electrically energizable multicharacter display mounted within said pushbutton so as to be visible from the top thereof;
a display drive printed circuit board beneath said panel common to said switches and having a plurality of apertures therein, one for each of said pushbuttons;
each said switch having sliding connector means comprising stationary contacts mounted on the rim of the associated aperture and connected to the display drive printed circuit on said board and movable contacts mounted on said pushbutton and connected to said display;
and means whereby said display is controlled through said display drive printed circuit board and said control circuitry printed circuit board in response to operation of said pushbutton switches.

Abstract
An integral multiswitch display panel (FIG. 3) having a plurality of pushbutton switches (A1-4, B1-4, C1-4, D1-4) mounted thereon along with a signal lamp (16) for each switch. A control circuitry P.C. board (44) and a display drive P.C. board (10) are common to all the switches with the control contacts (40, 42) of the switches controlling the displays (24) within the respective pushbuttons to provide on-off or alpha-numeric informational indications in response to operation of the bushbutton switches. The printed circuit lines of the control circuitry P.C. board (44) are connected through hermetically sealed connectors (50, 52, 54) at the bottom of the display panel to external controlled circuits with at least some of these lines being connected to the display drive P.C. board (10) for controlling the displays (24). The pushbuttons are environmentally sealed by a common seal (8) to prevent dirt, water, and the like from entering inside the panel housing (2, 4).
