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).
