Abstract: An antenna system for a vehicle includes a housing defining an interior space having a center. A component is provided for at least one of transmitting and receiving signals indicative of a vehicle condition. A loop antenna is provided in the interior space and electrically connected to the component. A parasitic element is provided for increasing a signal strength of the antenna system. The parasitic element extends from a first end to a second end spaced from the first end by a gap.

Abstract: An electrical switch (10) includes first and second spaced contacts (52, 56), and a rocking contact (80) having first and second arms (90, 92) in electrical contact with each other. A support (60) supports the rocking contact (80) for rocking movement in opposite first and second directions. The first arm (90) moves into engagement with the first contact (52) when the rocking contact (80) rocks in the first direction, and the second arm (92) moves into engagement with the second contact (56) when the rocking contact (80) rocks in the second direction. The switch (10) includes a member (20, 36) which pivots to effect rocking movement of the rocking contact (80) in the first and second directions. The member (20, 36) pivots in one direction a first distance to cause the first arm (90) to engage the first contact (52) and pivots in the one direction a second distance beyond the first distance to cause the first arm to slide on the first contact.

Abstract: A switch module for connection to an electrical circuit comprises a manually actuated ON/OFF switch mechanism mounted on a molded plastic case and two or more bus bars built integrally into the structure of the case, as by an insert molding process. The bus bars project out of the case at their ends, the exposed ends serving as terminals for electrical connection with the circuit and as spring contacts within the switch mechanism. The push button switch mechanism is an improvement over prior switches, having a single spring controlling both the push button and the shorting bar, and having positive alignment of the shorting bar and bus bar ends achieved by the pre-positioning of the bus bar ends in direct lateral sliding contact with the push button sidewall and sidewall-mounted shorting bar.
