ensure lights will not remain on forever if forgotten to turn them off.

timer and stretch on-time. Applications: staircases, basements, storage rooms, front door light-

A short push turns on with delay1* while a longer push turns on with delay2*. Repeated short/long
pushing during on-time will retrigger timer accordingly. Load will turn off when time elapses even
when pushbutton is held down.
