Abstract: A speed-limit setup meter includes a meter, which has a housing, a mounting frame at the bottom side of the housing, and a faceplate at the front side of the housing, a link pivotally mounted inside the housing, a pointer fixedly fastened to the front end of the link and kept in proximity to the speed-limit setup meter, and an adjustment device fixedly fastened to the rear end of the link outside the rear side of the housing for turning with the hand to rotate the pointer over the speed-limit setup meter.

Abstract: A conducting structure used in a meter is disclosed to include a plurality of electrically conducting support rods mounted inside the casing of the meter to support circuit boards of the meter at different elevations and to electrically connect the circuit boards to one another for transmission of signal and power.

Abstract: An illumination structure installed in a meter is disclosed to include a plurality of light emitting elements, for example, LEDs provided at a circuit board right below the center of a faceplate of the meter for emitting light toward the pointer of the meter, a light diffusion portion formed of a part of the faceplate of the meter through a sandblasting process for diffusing light in all directions in the space above the faceplate, and a light guide board mounted inside the meter between the circuit board and the faceplate around the LEDs for guiding the light from the LEDs toward the light diffusion portion to illuminate the faceplate.
