    • 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.
    • 自动开关控制装置适合于墙上的开关,以便在开启位置和关闭位置之间移动开关的肘杆。 自动开关控制通常包括壳体和由壳体可旋转地支撑的轮构件。 车轮构件具有带有斜面的凸轮构件。 电动机可操作以使轮构件围绕大致垂直于壁的旋转轴旋转。 第一柱塞机构具有第一弹簧构件,其可操作以推动第一凸轮从动件与斜面的滑动接合。 第二柱塞机构具有第二弹簧构件,该第二弹簧构件可操作以推动第二凸轮从动件与斜面的滑动接合。 当自动切换控制装置安装在开关上时,第二柱塞机构设置在肘节与第一柱塞机构相反的一侧。 电动机可操作以旋转凸轮构件以将第一柱塞机构定位在缩回状态,并将第二柱塞机构定位在可操作以将肘杆移动到接通位置的延伸状态。
