Abstract

A sliding type switch includes a non-conductive housing enclosing chamber. A non-conductive board is securely mounted in an upper portion of the chamber and includes at least three pairs of slots defined therein. At least three pairs of conductive prongs respectively extend through the slots in the board, each conductive prong having a conductive shoe formed at a bottom thereof. A non-conductive slide member is slidably mounted in a lower portion of the chamber. The slide member defines two elongated troughs in which an inner bottom wall defining each elongated trough has a stub formed thereon. An elastic element is mounted in each trough and includes a mediate portion with a hole defined therein through which the associated stub extends for positioning the elastic element, and a first limb and a second limb which extend upwardly from the mediate portion and away from each other. At least one conductor is mounted on each elastic element for conjoined movement therewith so as to engage electrically with two pairs of the three pairs of conductive shoes. The elastic element biases the conductor to engage with the conductive shoes.

Claims

1. A sliding type switch comprising:

a non-conductive housing enclosing a chamber and including a flange extending along a mediate portion of an inner periphery thereof, thereby separating the chamber into an upper portion and a lower portion, the housing further comprising a first slot defined in a bottom thereof;

a non-conductive board securely mounted in the upper portion of the chamber and including at least three pairs of second slots defined therein;

at least three pairs of conductive prongs respectively extending through the second slots in the board, each said conductive prong having a conductive shoe formed at a bottom thereof;

a non-conductive slide member slidably mounted in the lower portion of the chamber and having a knob extending through the first slot, the knob being slidably movable in the first slot for selectively positioning the slide member within the chamber, the slide member further defining two elongated troughs in which an inner bottom wall defining each said elongated trough has a stub formed thereon;

an elastic element mounted in each said trough and including a mediate portion with a hole defined therein through which the associated stub extends for positioning the elastic element, and a first limb and a second limb which extend upwardly from the mediate portion and away from each other;

at least one conductor mounted on each said elastic element for conjoined movement therewith so as to engage electrically with two pairs of the three pairs of conductive shoes, the elastic element biasing said at least one conductor to engage with said conductive shoes.

2. The sliding type switch assembly according to claim 1, wherein said at least one conductor is substantially inverted U-shaped and includes two downwardly extending ends for respectively bearing against the first and second limbs of the associated elastic element from outer sides of the first and second limbs.
