Abstract
Abstract The present invention relates to a slide switch having one or more manually actuated switches of miniature size adapted for use on a printed circuit board or the like. More particularly, the invention includes a channel-containing base, two face to face strip form contacts in the channel with legs thereon depending from opposite edges of the base. A cover contains a slidable spring carrier which in turn carries a spring having a conductive limb thereon for removable engagement with the two face to face contacts thereby completing a circuit from one contact to the other.

Claim 1
Independent Claim
344 words
A slide switch comprising: a. a base of insulating material having a plurality of channels each extending across the upper surface, further a plurality of apertures positioned adjacent the outer edges of each channel and extending vertically through the base; b. a plurality of contacts stamped and formed from conductive material, each having a first part providing a leg and a second part providing a contact surface at its free end, said parts being generally at right angles one to the other, said leg extending through an aperture and depending from the base, said second part positioned in the channel with the contact surface facing inwardly and formed into a part cylindrical shape opening downwardly, said contact surface being located near the contact surface of a contact positioned in the same channel and extending inwardly from the opposite side; c. a box-like cover of insulating material having apertures spaced along its upper surface and mounted on the base thereby providing an interior space, said apertures being in alignment with the channels on the base surface; d. a plurality of carriers of insulating material, each positioned in the interior space in alignment with an overhead aperture and underlying channel, each carrier having an arm extending through an aperture and a vertical cavity in the undersurface adjacent one end; and e. a plurality of hairpin-shaped springs stamped and formed from conductive material, each positioned between a channel and an overlying carrier, a first limb of each spring being sinuous with the free end thereof formed in a part cylindrical shape opening upwardly and being in removable electrical engagement with one or both of the contact surfaces in the underlying channel, and a second limb having its free end bent upwardly at right angles thereto and loosely positioned in the carrier cavity to permit limited sliding movement of the spring independent of the carrier movement so that as the carrier moves the part cylindrical free end on the spring's first limb into engagement with the two facing contact surfaces, the part cylindrical free end centers itself thereinbetween.
