DEFINITION

Classification: 337/127

(under subclass 126) Subject matter including means whereby

the opening, or the closing, of the switch contacts takes place at an appreciable interval of time after an actuating force is applied to the contact actuating means or the timing of the contact open or contact closed interval is effected by varying the energizing current applied to the device.

(1) Note. For other delayed action or timing means employed in devices of this class, see SEARCH THIS CLASS, SUBCLASS below.
