<p>SLIDE SWITCH A row of three stationary electric contacts is mounted on an insulating base for a metal housing in which a bridging contact carried by an insulating slider is movable lengthwise of the row from a position bridging the middle stationary contact and either of the end contacts to a position bridging the middle contact and the other end contact. When the bridging contact is moved into engagement with an end contact the slider also moves a metal grounding contact into engagement with the end contact that is not engaged by the bridging contact at that time, whereby the end contact engaged by the grounding contact is electrically connected by it to the metal housing which the grounding contact always engages.</p> |
