Can use the Matchbox Relay for other electrical loads?
Yes, the Matchbox relay can be used to control horns, sunroofs, alarms, cooling fans or any electrical load up to 20 amps. Q: Can I run both the high beam and the low beam at the same time with my Matchbox Relay? Most likely you can, but it depends on the wattage of the lamps you are using. Since each of the Matchboxs internal relays can handle 20 amps, on a 12-volt electrical system each of the Matchbox’s relays (and there are two of them in a single Matchbox) can handle as much as 240 watts of lighting but that is only when you are energizing one relay at a time. If you are going to have both relays energized at the same time you have to keep the total wattage across both relays below the 240 watts of total power As long as the combined wattage of all lamps being fed by both relays is less than 240 watts you should be OK from a power management standpoint. Read on though as you should consider the thermal management concerns among other factors. (Note: On a 6-Volt system with a 6 vol
