Hi, I have a basic setup of a 5" LCD TV, a video transmitter and a receiver. Each piece of equipment is powered by 3 12v batteries which are each wired to 3 seperate switches, allowing me to turn the power on and off from one location.
However, I wondered if I could replace these 3 switches with just one switch, allowing me to power all 3 devices by just the one switch.
Is this possible?
Regards,
Sean
As long as you choose a switch with a high enough current rating to handle all three, it should work...
I'm not saying you won't run into problems by doing so how ever, in theory that should work as long as the switch and single battery you select will handle the load. There is a remote possibility how ever, that one of the devices could be using a raised common from the (-) rail for example, to derive a - offset/bipolar source from the assumed non-shared supply.
