ABSTRACT:
A switching device includes a casing having two opposite lateral walls, two spaced-apart terminal plates secured in a bottom wall of the casing, and a slide unit. The lateral walls respectively have opposite guide faces that extend downwardly and inclinedly toward each other, and opposite limiting faces that extend downwardly and respectively from the guide faces toward the bottom wall. The slide unit includes a slide piece mounted movably within the casing, and a conductive piece connected to the slide piece and disposed between the limiting faces. The slide piece is slidable along the guide faces to move the conductive piece between first and second positions, where the conductive piece contacts conductively and moves away from the terminal plates, respectively. A biasing unit is provided for biasing the conductive piece to the second position.
