Illumination-type rotary variable resistor |
摘要 |
An illumination-type rotary variable resistor. A housing includes a round bottom plate, a cylindrical outer wall protruding in a first direction, and a cylinder. This housing houses an annular insulating substrate having a resistor film and LED conductive film on its surface facing in the first direction. An operating knob includes a cylindrical operating member rotatably fitted to the cylinder and a flange having a resistor slider and LED slider on a face in a second direction being opposite to the first direction. The operating member has a through hole along the first direction, and the flange is attached to the operating member in the second direction. A cover covers the housing and flange. A surface-mount LED is disposed in the through hole at an end which is facing in the second direction. A resistor slider slides on the resistor film, and a LED slider slides on the LED conductive film.
