    摘要: A power switch control module for a power window control circuit of a motor vehicle. The control module incorporates a printed circuit board, a plurality of switch contacts secured to the printed circuit board, a plurality of connector terminals also secured to the printed circuit board, a plurality of high current traces formed on an upper surface of the printed circuit board for coupling selected pairs of the switch contacts and connector terminals electrically together, and a switch control. The switch control is mounted in a frame member for pivotal movement relative to the printed circuit board and is movable between up and down positions. When in the up position the switch control electrically couples a first selected pair of switch contacts and when in the down position the switch control electrically couples a second selected pair of the switch contacts. The high current traces are capable of handling about 20-80 amps of current. Since the high current traces are formed on the upper surface of the printed circuit board, no injection molding, tooling or techniques are required for construction of the module as typically required with prior art control modules. Also, the undersurface of the printed circuit board can advantageously be used to mount other electronic components of the control circuit.

    摘要: The present invention relates to a molded housing having an integral acoustic chamber and a plurality of post members which engage the printed circuit board contained therein to preclude rattling. As sound waves are generated within the acoustic chamber the sound waves travel along a directed path thereby enhancing the audible level of the sound waves allowed to escape the housing.
