The invention is a control device intended for the choice and the selection of functions in a vehicle. The device comprises three binary active sensors, arranged on an electronic board fixed in a case, the sensors switch on the passage of passive markers arranged on a support displaceable by means of a manipulable control element. The support being displaceable in translation along a first longitudinal main axis towards a front position and a rear position and perpendicularly along a second transversal main axis towards a right position and a left position, and in rotation about a normal axis perpendicular to the main axes in the clockwise direction and in the anticlockwise direction. The marker support and the control element are moreover connected to an indexing and return means which biases them permanently towards a neutral position.

A digital camera is provided that includes a rotation operation member unit having a circumferential surface, a sheet fixed to the circumferential surface of the rotation operation member unit, and a photo reflector provided at a position facing the sheet that applies light to the sheet and detects the light reflected from the sheet. In the sheet, regions that reflect light to a level at which a photo reflector can detect the reflected light and regions that do not reflect the light are alternately formed. Additionally, a convex portion that is formed in the sheet in the rotation axis direction of the rotation operation member unit, and a concave portion that is formed in the rotation axis direction of the rotation operation member unit are engaged.

A non-contact button assembly for a powered surgical instrument includes a light emitter, a rocker switch, and a button shaft. The rocker switch defines a through passage about a longitudinal axis of the button assembly. The button shaft is disposed within the through passage. The button shaft includes a proximal portion, a distal portion, and a flange positioned therebetween. The button shaft has a deactivated position such that the button shaft is configured to prevent light from the light emitter from illuminating a light detector and the button shaft has an activated position such that the button shaft is configured to permit light emitted from the light emitter to illuminate the light detector.

An input device for an electrical device includes a base which can be attached to the electrical device and has at least one light source for producing a measurement beam, and at least one sensor for detecting the reflected measurement beam. An input actuator is movable in relation to the base and includes a plurality of reflection bodies for deflecting the measurement beam onto the sensor. Each reflection body has an entry area for entry of the measurement beam into the reflection body, at least one reflection surface for reflecting the measurement beam, and an outlet area for outlet of the measurement beam from the reflection body.

Mounting an agent on a cover of on an enclosure of an electronic device such that changing a physical location of the cover changes a location of the agent. In response to a change in the physical location of the cover, detecting a change in location of the agent with a sensor. Reading a transmitted signal from the sensor by a controller and changing a status of the electronic device according to instructions from the controller, the instructions being configured according to the transmitted signal of the sensor.
