Double beam switch contact
An LCD counter assembly including a housing that houses an LCD display at a first end and a printed circuit board (PCB) assembly at a second end opposite the first end. A diffuser is intermediate the PCB assembly and the LCD display, the LCD display and the PCB assembly in electrical contact with a connector that provides electrical signals from the PCB assembly to the LCD. The first end of the housing includes an aperture through which the LCD display is readily visible to an observer. The PCB assembly may include a backlight to improve the visibility of the LCD display. The PCB assembly further includes a PCB having a printed circuit and a plurality of pads, a single piece, double beam, activation and trigger switch combination assembled to the board, the board configured to receive the double beam activation and trigger switch combination and a removable tab to separate the activation switch in the double beam combination from one of the plurality of pads.
1. A single piece, double beam connector comprising a double beam contact, said contact comprising:
a first contact which is an activation switch comprising a first beam;
a second contact which is a trigger switch comprising a second beam, the trigger switch (a) adjacent to the activation switch, and (b) movable from a first position to a second position parallel with the activation switch under an applied force, the trigger switch and the activation switch being stamped from a single piece of conductive metal and connected thereto; and
a tab formed of a dielectric material which, when in position, isolates the activation switch from electrical contact with a conductive pad when in position, and when removed, allows the activation switch contact with the conductive pad.
2. The single piece, double beam connector of claim 1 further including a pair of arms substantially at right angles to the activation switch and trigger switch.
3. The single piece, double beam connector of claim 2 wherein each arm of the pair of arms includes at least one finger.
