Abstract
An automatic switch control includes a wheel member having a cam member with a ramp surface. A first plunger mechanism has a first spring member that is operable to urge a first cam follower into sliding engagement with the ramp surface. A second plunger mechanism has a second spring member that is operable to urge a second cam follower into sliding engagement with the ramp surface. The second plunger mechanism is disposed on an opposite side of the toggle from the first plunger mechanism when the automatic switch control is installed over the switch. An electric motor is operable to rotate the cam member to position the first plunger mechanism in a retracted condition and to position the second plunger mechanism in an extended condition that is operable to move the toggle to the on position.
