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).

Abstract: A reduced size pushbutton (6) switch having a plurality of contact pairs (40, 42, 44, 46) arranged angularly for radial actuation by normally-open cams (34c) or normally-closed cams (34d) on a vertically reciprocated actuator block (34) by a snap-action mechansim (30c, 30d, 36, 38 or 66, 68a). The contact pairs are electrically connected to a control circuitry PC board (52) which provides an output control as well as controlling a multi-character alpha-numeric display mounted within the pushbutton. This display includes a light source (22), a display (24) and movable (14) and stationary (12) contacts connecting the light source to a display drive PC board (10) which may be connected to the control circuitry PC board to afford control of the display by some of the contact pairs. A seal (8) between the front panel and the display PC board hugs the pushbutton to prevent dirt from entering the switch base (54).
