Abstract
The present invention relates to encoder-switch assemblies, such as electromechanical roller-key assemblies comprising an encoder part and two or more actuator switches. The encoder part operates in accordance to magnetic, optical and/or electromechanical principles and provides one or several electrical output signals indicating the instantaneous change of angular position of a rotating roller or tuning wheel. The actuator switches provide two or more electrical output signals indicating a plurality of positions of the roller-key or wheel of the assembly.
Claims34
A roller-key assembly comprising,
- a carrier,
- a roller member supported by the carrier and being rotatably mounted in relation to the carrier,
- a coding member engaging the roller member in a manner so as to rotate when the roller member rotates,
- the carrier being mounted in a supporting structure and being at least partly displaceable relative to the supporting structure so as to render the roller member displaceable from an initial position to a selected displaced position of at least two predetermined displaced positions,
- means for detecting rotation of the coding member in relation to the supporting structure,
- means for generating a return spring force that returns the roller member to the initial position from the selected displaced position,
- switching means being adapted to indicate the selected displaced position of the roller member, and
- a sealing foil arranged between the switching means and the roller member so as to separate the switching means from the roller member by a substantially moisture- or watertight layer, wherein the roller member is mounted within a substantially moisture- or watertight well formed by the supporting structure and the sealing foil, said well having an opening arranged oppositely to the sealing foil.
A roller-key assembly comprising,
- a carrier,
- a roller member supported by the carrier and being rotatably mounted in relation to the carrier,
- a coding member engaging the roller member in a manner so as to rotate when the roller member rotates,
- the carrier being mounted in a frame and being at least partly displaceable relative to the frame so as to render the roller member displaceable from an initial position to a selected displaced position of at least two predetermined displaced positions,
- means for detecting rotation of the coding member in relation to the frame,
- wherein the carrier comprises a first and a second part, the first part being substantially rigidly connected to the frame, the second part being adapted to support the roller member and being displaceable relative to the first part of the carrier, the second part comprising means for generating a return spring force that returns the roller member to the initial position from the selected displaced position, the return spring force generating means forming an integral part of the second part of the carrier.
