Switch Delema, 5 switches 2 purposes
Ok so i have 5 gauges wired with a power wire for the gauge and a seperate power wire for the light. i have 5 spst switches wired for the main power and the lights. what i want to do is have those 5 switches turn on the gauges and their lights together individually. but i want all the lights controlled by the one seperate switch, basically i need some way to do this other than 5 relays. can this be done by wiring transistors in line some how? the lights are just a single led so the power to tbe light is 12v probably about 20-30 mA how could i go about doing this? i have the 2 15 packs of transistors from radio shack, both npn and pnp. any help would be great. and if it can be done using strictly radio shack parts that would be best. i cannot order things online easily. thanks!
