  • Patent number: 7060915
    Abstract: A miniature switching device has an operating member (14) with an upstanding button (26) that can be rapidly slid in any one of four horizontal directions to close any one of four switches in a casing (12). A sheet metal conducting member (28) has a flat base portion (60) that lies in the casing under said operating member, and has four upstanding plates (62) that extend from bends (63) at the periphery of the base portion. Each plate has an upper end (81) that lies against a side of the operating member so horizontal movement of the operating member tilts a plate about a corresponding bend. Each plate has a finger (83) that extends largely horizontally from the plate and that engages a corresponding contact (56) on a bottom wall of the casing.
