Abstract
A button includes an electronic circuit. The electronic circuit includes a potentiometer having a first center tap connected to an output terminal. A second center tap is connected to a first terminal of the potentiometer via a first resistor, to a first supply terminal via a second resistor, and to a second supply terminal via a third resistor. The resistance of the second resistor is equal to (1−kx)Rx. The resistance of the third resistor is equal to kxRx. A third center tap is connected to a second terminal of the potentiometer via a fourth resistor, to the first supply terminal via a fifth resistor, and to the second supply terminal via a sixth resistor. The resistance of the fifth resistor is equal to (1−ky)Ry. The value of the sixth resistor is equal to kyRy.
Claims10
A button comprising:
- an electronic circuit equipped with:
- a cursor capable of moving along a predetermined trajectory between a proximal position and a distal position;
- a first power supply terminal and a second power supply terminal able to be connected to respective poles of a power supply source;
- a first output terminal and a second output terminal, between which is delivered a voltage representing the position of the cursor along its trajectory;
- and
- a linear potentiometer comprising:
- a first connection terminal and a second connection terminal respectively connected to the first power supply terminal and the second power supply terminal;
- and
- a first center tap connected to the first output terminal, with a resistance between the first center tap and the second connection terminal continuously varying from a minimum value to a maximum value when the cursor is moved from one of the proximal position and the distal position to the other one of the proximal position and the distal position;
- and
- a return mechanism that automatically returns the cursor to a neutral position in the absence of external stress;
- wherein the electronic circuit comprises:
- a second center tap connected:
- to the first connection terminal for connecting the potentiometer via a first resistor;
- to the first power supply terminal via a second resistor, the value of the second resistor being equal to (1−kx)Rx, where kx is a coefficient ranging between 0 and 1, and Rx is a constant value of a first total resistance;
- and
- to the second power supply terminal via a third resistor, the value of the third resistor being equal to kxRx;
- and
- a third center tap connected:
- to the second connection terminal for connecting the potentiometer via a fourth resistor;
- to the first power supply terminal via a fifth resistor, the value of the fifth resistor being equal to (1−ky) Ry, where ky is a coefficient ranging between 0 and 1, and Ry is a constant value of a second total resistance;
- and
- to the second power supply terminal via a sixth resistor, the value of the sixth resistor being equal to kyRy.
