How do I calculate the needed current rating on an on/off switch used to power 12V or 24V G4 Halogen bulbs with either a 12VAC, 24VAC or 12VDC and 24VDC power source. Say I wanted to operate 2, 35watt G4 Halogen bulbs using 12VDC power. How many amps would the switch need to be rated for. And what would it need to be rated for if it was a 24VDC system or AC system? Is there a formula so no matter the wattage I can figure it out? Thank you, David |
