ABSTRACT:
In a preferred embodiment, a disk-shaped wafer insertable into a three-way bulb-socket, thereby becomes an insertable and removable switch converter-device to convert a three-way socket to a one-way bulb-socket and/or back-to a three-way bulb-socket, includes an annular insulation ring and mounted on an upper radially inward face portion of the annular insulation ring, is located an electrically conductive disk having a raised central portion and having opposite upper and lower surfaces thereof. The lower radially outward conductive disk surface is contactable with a bottom-of-socket radially-outward electrical contact of the three-way bulb-socket. The upper conductive disk surface at the raised or electrically-insulated central portion is contactable with a three-way light bulb's role socket insertable member's lower-end bulb's two electrical contacts, one central, the other a concentric ring. The central portion's lower surface is sufficiently raised or otherwise insulated against electrical contact with the socket's central electrically-conductive contact. In another embodiment devoid of the raised central portion, a lower mounted central insulation disk insulates the central conductive portion from inoperatively contacting other electricity-conductive socket structure. Other perferred embodiments include disk-handled structures for lifting the switch converter device from a socket space, and in another embodiment, a magnetic handled structure for attracting, attaching to and removing the switch converter device from a socket space.
