LED's draw very little power, take the wattage and dived by 12 to get the amperage, for interior use you should be able to wire one pin of a switch to a + source and then the other pin to your led's +, you'll have to ground the LED's - side to a body - somewhere that's convenient. Whatever amperage your drawing with all of your LED's put a slightly higher amperage fuse between the switch and your + source and make sure the switch is rated for at least or higher amperage than your drawing.
