I run 4 turnouts off of one switch. I have 5 sets of 2 turnouts that run off of one switch each. I have never had a problem with them. Are yours hooked to the A/C output? are the wires big enough?
The way I have it wired is as follows: One (three wire RBG) going under the table. Then that is spliced into two, one to each switch. From what I understand from above I should have one long wire from the button to each switch and not one wire that is spliced to go to each switch?
