Illuminated rocker switch Yellow / Green / Red / Blue pack of 20 They are currently used in automobiles, racing cars, RVs, transport vehicles, heavy vehicles, off-roaders and almost anything that uses a 12 volt power source. Features Simple installation. All you need is a 20mm (3/4 '') hole and the switch sits nicely in it; no more square cutouts. Pole with LED for grounding. SPST 2-pole design (on / off).   Technical data Material: performance in ABS plastic Dielectric strength: 1500 V (minimum) Insulation resistance: 100 megohms (minimum) Working voltage: AC 150V / 250 V, DC 12 V Working current: 10A / 16A maximum 20A Electrical lifespan: over 10000 cycles Lifespan mechanics: over 50000 cycles Weight: 80g 20 round rocker switches (5 Red, 5 Green, 5 Yellow, 5 Blue)   Note Depending on the color, the LED draws between 8 and 10 mA. If you are using a resistor with more than 12V, connect a resistor in series with the connection to the yellow pin. Do not connect it directly to the power supply.
