Rocker actuator potentiometer
A manual control for an electronic apparatus includes a manually activated rocker actuator mechanism coupled to a magnet source. The magnet source is in a rest position relative to a Variable Hall effect sensor device when the rocker actuator mechanism is in a rest position. A variable output signal from the sensor device is substantially at a minimum value when the magnet source is in the rest position relative to the sensor device. The magnet source is in a maximum position relative to the sensor device when the rocker actuator mechanism is in a maximum position. The variable output signal is substantially at a maximum value when the magnet source is in the maximum position relative to the sensor device.
