    摘要: 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).

    摘要: A large overtravel operating lever for a plunger (6) actuated miniature precision snap action switch (2) that includes a supporting bracket (8) having a cantilever strip (8c) extending over the plunger (6). A pivot (10) couples a lever arm (12) to the end of the cantilever strip above the plunger. A cam strip (16) is riveted to the lever arm (12) and extends between the plunger and the pivot and is formed with a nib (16c) for depressing the plunger and a constant radius contour (16b) leading from the nib for large overtravel of the lever arm. The cam strip (16) extends through a hole (8h) in the cantilever strip for clearance on movement and a stop (16e) abuts the latter to limit counterclockwise rotation of the lever arm to off position. A metal strip (18) riveted to the bracket extends across the plunger to prevent wear.
