Automatic Door Switch

Where indicated on the plan, clothes closets shall be equipped with automatic door switch to connect the light when the door is open. Fig. 266 is placed in the door frame in such position that electric contact is made by release of the projecting pin as the door is opened. When the door is closed, the pin is depressed and the light is extinguished

Plug Receptacles

Plug receptacles shall be selected from the styles shown in Figs. 267,a, b, c or d.

Fig. 267,a is the disappearing - door type with beveled-edge brass cover plate finished to match surrounding hardware. In this receptacle the doors are pushed inward by the insertion of the plug and upon its withdrawal close automatically, effectually excluding dirt and concealing the live terminals. It is the latest and best plug receptacle obtainable.

Fig. 267,b is of the Chapman type with beveled-edge brass cover plate finished to match surrounding hardware. In this receptacle the doors open outward but are flush whether the plug is in or out.

Fig. 267,c is of the screw-plug type with beveled-edge brass cover plate finished to match surrounding hardware. By many this is preferred for apartment use as it will receive any style of Edison attachment plug.
