The operating unit for a vehicle includes an operating element having an operating surface movable in an actuating direction from a rest position into a function-triggering position and from the function-triggering position back to the rest position by means of depressing. A parallel guiding device ensures that the operating surface moves in parallel. The parallel guiding device is provided with at least one pair of engaging first and second levers which are mounted in an articulated manner with play on support elements being in turn connected to the operating element. The support elements are axially guided on a carrier element. The levers are pivotably mounted on bearing blocks, substantially free of play, so that the operating element behaves substantially free of play in directions transverse to the depressing movement. The parallel guiding device is designed in compliance with tolerances that are comparatively easy to realize in terms of manufacture.

An electric switch used in an electric device having a motor is provided. The electric switch comprises a switch housing, a plunger extending from the switch housing and switching from an off position into an on position of at least one contact of a contact system arranged within the switch housing via a movement, a circuit board; and a changeover device for changing a direction of rotation of the motor. The changeover device comprises a position encoder operated from outside, the position encoder is directly connected to a contact arm via two contact tongues; one contact tongue interacts with one conducting path to create a contact for the clockwise rotation of the motor in one position of the position encoder, and/or the other contact tongue interacts with other conducting paths to create a contact for the counterclockwise rotation of the motor in another position of the position encoder.

The invention relates to an electric switch for electrical devices having a circuit board immovably arranged in a switch housing said circuit board including on one of its surfaces the contact paths of a contact system as well as contact surfaces in the form of potentiometer tracks. The contact paths interact with sliding contacts of the contact system and the potentiometer tracks interact with additional sliding contacts in order to set the revolutions per minute or the torque of the electric motor, wherein movement of the plunger causes the sliding contacts of the contact system to come into contact with the associated contact paths, and, in this position of the plunger, which is the on position of the switch, the sliding contacts used for changing the direction of rotation are in the same way already in contact with the associated potentiometer tracks on the circuit board.

A luminous keyboard includes plural keys, a membrane switch circuit board and a light-emitting element. The membrane switch circuit board includes an upper wiring plate, a lower wiring plate, a conductor line pattern, a separation layer and an etched line pattern. The lower wiring plate includes a wiring plate opening. The conductor line pattern is arranged between the upper wiring plate and the lower wiring plate. The etched line pattern is arranged between the separation layer and the lower wiring plate. The etched line pattern is exposed through the wiring plate opening. The light-emitting element is electrically connected with the etched line pattern through the wiring plate opening in order to acquire electric power. Consequently, it is not necessary to install the illumination circuit board to provide the electric power to the light-emitting element.

A touch pad input device includes a touch pad having a touch area formed on an upper surface thereof; a switch installed under the touch pad to generate a signal when a downward external force more than a reference value is applied; a restoring means configured to support elastically upward a lower surface of the touch pad; and a housing in which the touch pad, the switch and the restoring means are installed. Even when only one switch is installed under the touch pad, the switch can be stably operated when each area of the touch pad is pushed, and since the separate printed circuit board for transmitting the pushing signal of the switch is omitted, it is possible to provide a simple internal structure and to reduce a manufacturing cost, and all functions of a mouse and an arrow key can be performed.

A sealed electronic module (1) including at least one actionable part (2), the module (1) including a case (2) having: a watertight compartment (4) containing a printed circuit board (5), the compartment (4) being formed by a housing (13) with a unique opening (20), the housing (13) including the printed circuit board (5), and a sealing element (6a, 6b) configured for closing tightly the unique opening (20) by being fixed to the housing (13) and the printed circuit board (5).
