  • Publication number: 20030226684
    Abstract: There is disclosed structure which overcomes the deficiencies with respect to prior art devices by providing a wiring device such as a receptacle or a spring loaded switch having a paddle that pivots about its upper end and is biased to assume the same at rest position when either in its on position or off position. Repeated pressing and releasing the lower portion of the face of the switch paddle alternately closes and opens a set of contacts within the switch to alternately connect and disconnect a load from a source of electricity each time the paddle is pressed. Thus, regardless of whether adjacent switches are on-off switches or 3-way switches, they will always be in alignment. An on-off indicator such as a small light, a flag in a window, a mechanical protrusion of the like can be provided to indicate to a user when the contacts of the switch are opened or closed.
