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.
