ABSTRACT:
In accordance with the present invention, there is provided an electric reversing switch comprising an insulated base having an elongated cavity defined therein. An elongated insulation member is provided for oscillatory motion about an axis through the cavity through an angular interval between a first and second position. Conductive bridging elements are provided on the ends of the insulation member and biased outwardly from the insulation member along the axis thereof. A first pair comprising first and second fixed contacts is supported in the base, each including a contact portion within the cavity and being symmetrical disposed relative to the axis through the cavity. A second pair comprising third and fourth fixed contacts is provided within the housing, each including contact portions within the cavity wherein one contact portion is adjacent and spaced angularly from the contact portion of the first fixed contact and another contact portion is adjacent and spaced angularly from the contacting portion of the second fixed contact. Means are provided for oscillating the insulation member between a first position wherein the bridging element at one end of the insulation member electrically connects the contact portions of the first and third fixed contacts and the bridging element at the other end of the insulation member electrically connects the contact portions fo the second and fourth fixed contacts, and a second position wherein the bridging elements electrically connct the first fixed contact with the fourth fixed contact, and the second fixed contact with a third fixed contact.
