ABSTRACT:
The indicator light, preferably a LED, is mounted in a insulating housing secured by a pair of legs with relatively broad feet which are soldered to conductive pads on the surface of a printed circuit board. Preferably, the printed circuit board uses "surface mount" technology. The leads of the LED are spot welded to the legs to make electrical connections between the LED and the circuit board. The structure elevates the LED above the board surface, and/or allows mounting the LED close to the edge of the circuit board, and/or allows the light from the LED to be directed parallel to the board surface. A particularly advantageous use of the structure is one in which printed circuit boards are arranged in an array with the boards parallel to one another and the LED mounting structures near the end of each board so as to provide maximum visibility of the LEDs from many angles so as to quickly indicate equipment functional status to an operator or trouble-shooter. In the manufacturing method, the leg structures are stamped and formed along the edge of a pre-plated and selectively solder-coated strip, with prongs being formed on each leg. The prongs then are pushed into recesses in a plastic body. The LED is inserted and the leads are spot welded to the legs. Then, the assembly is broken off of the strip along a previously formed break-line.
