Abstract
A combined gravity operated light socket and switch including a base, fastening means extending from one side thereof and a dielectric housing extending from the other side, the housing being divided into two adjacent chambers. The first chamber is open-ended forming a light socket and the second chamber houses a switching mechanism. The switch includes a headed co-axial shaft extending between the chambers with the head acting as a contact in the base of the socket and the opposite end carrying a flat centrally flanged teeter-totter element supporting a rolling ball and arranged for predetermined angular movement upon angular shifting of the housing. The angular movement of the flat element is limited by stop means, one of which is a contact, thereby producing an on-off status depending on the angular placement of the unit.
