摘要:
An automatic switch control fits over a switch on a wall to move a toggle of the switch between an on position and an off position. The automatic switch control generally includes a housing and a wheel member rotatably supported by the housing. The wheel member has a cam member with a ramp surface. An electric motor is operable to rotate the wheel member about an axis of rotation that is generally perpendicular to the wall. 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. The 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.
