Abstract: Disclosed is a device (30) for manually controlling the position of switching means which have two extreme positions A and C and an intermediate position B. Said device comprises a crank (5) and a crankpin (6). The invention is characterized by the fact that the device comprises a translationally movable sliding member (1) that has a neutral position and is provided with guideways (20, 21), within which the crankpin (6) is displaced. Said guideways allow the crankpin to be guided towards three areas of the sliding member, in which the position thereof is stable and which correspond to the three positions of the switching means, when the sliding member is moved towards the neutral position. The inventive device has the advantage of being simple while allowing a change in the state of the motor which operates the closing element, darkening element, or sun-shading element, or sun-shading element to be controlled by means of a single movement of a rod (14).

Abstract: A remote control electrical switch with omnidirectional access provides remote control of electrically connected devices. The remote control electrical switch allows electrical devices to be controlled with minimal physical dexterity, easing the physical efforts required for typical electrical switching devices.

Instances of the switching mechanism can also include an illumination source to indicate the status of the remote control electrical switch from a visual perspective and/or to provide location of the switching mechanism in ambient light deficient areas.

Abstract: A micro-machined magnetic latching switch is described. A moveable micro-machined cantilever has a magnetic material and a longitudinal axis. The cantilever has a conducting layer. A permanent magnet produces a first magnetic field, which induces a magnetization in the magnetic material. The magnetization is characterized by a magnetization vector pointing in a direction along the longitudinal axis of the cantilever. The first magnetic field is approximately perpendicular to longitudinal axis. A three-dimensional solenoid coil produces a second magnetic field to switch the cantilever between a first stable state and a second stable state. The temporary current is input to the three-dimensional solenoid coil, producing the second magnetic field such that a component of the second magnetic field parallel to the longitudinal axis changes direction of the magnetization vector. The cantilever is thereby caused to switch between the first stable state and the second stable state.
