摘要： A low profile keyswitch (10) for attachment to a one-sided printed circuit board (62) has contact which laterally spaced prongs (66), (68), (80), (82) for connecting the contacts to more than one conductor (134), (134a), (136), (136a), in the printed circuit board (62) without requiring additional jumper wires. The low profile keyswitch (10) includes a return spring (18) mounted offset from the plunger body (14) and laterally spaced from the switch contacts (64) and (68) to isolate the switch contacts (64) and (68) from wear debris such as from the spring (18). The switch contacts (64), (68) have base portions (65), (79) mounted in parallel, laterally spaced slots (44), (54) in the base of the housing (12) to distribute forces on the contacts to reduce the likelihood of fractures caused by repetitive bending of the contacts (64), (68) as the keyswitch (10) moves between an open and a closed position.

摘要： Keyboard switch modules have connectors for attaching one module to another and to form a modular structural base assembly for constructing a custom key switch array which includes a foundation structural base module and a grouped keyswitch station arranged similarly to a typewriter key matrix. Accessory base modules of various keyswitch groupings can be attached to the foundation module to permit addition of accessory keys at virtually any location and in any desired number of switch modules. The keyboard switch module (45) or connectors are of the tongue-and-groove type, especially dovetail connectors formed by flanges (75) and recesses (77) on the modules. The modules include means for effecting an interference fit to interlock adjacent modules. Preferably this interlocking is achieved by means of crush ribs in the connector recesses which engage the connector flanges.
