Abstract: An arcuate switch plate assembly for a standard wall toggle switch comprising a convex base plate and a convex switch actuator wherein the convex actuator moves in an arc similar to the arc of the toggle switch.
Abstract: A capacitive element is introduced in series with the gate of a switching element in an automatic turn on/off circuit which automatically provides artificial light depending on the ambient light incident on a photo sensitive element of the circuit wherein the capacitive element holds an offset voltage which aids in turning on the switching element and provides a hysteresis in the system which counteracts a flickering effect common to automatic turn on/off circuits controlling an artificial light which employ a photo sensitive device.
