notes: label: Description (Brief)
content: A Schaefer keyed socket for an incandescent lamp. Hard rubber frame with brass fittings and plastic key. The brass base shell of a lamp is installed, and includes copper lead wires and cork insulator. The control is configured so that when key is in the on position, the key itself prevents release arms from being actuated. When key is turned to the off position, the release arms can be squeezed together, releasing the base pins of the lamp and allowing the lamp to be removed. Identified by donor as given him by William Wallace.
