A slide switch is disclosed which is contained within a molded housing. The contact blade of the slide switch is pivoted at its center and is biased into sliding engagement with first and second spaced contacts by a spring pressing in the region of the pivotal axis of the sliding blade. Electrical terminals are connected to or are integral with the first and second contacts. A third contact or insulation pedestal is aligned in a row with the first and second contacts, with the center contact being slightly higher than the end contacts. When the pivot of the blade moves to either side of the central contact, the contact blade tilts on the central contact with a snap action during contact make and contact break with respect to the one or both of the end contacts, with arcs drawn to the very end of the tilting contact blade. During the contact engagement action, the sliding blade slides over the end contact with wiping action which ensures clean contact surfaces for the contact blade and end contact when the sliding contact blade comes to rest. The third contact or pedestal serves as a tilt stop for the sliding contact blade when it is moved to the open position and can be connected to a third conductive terminal.
