Switch wiring help....
I need some switch wiring help. I currently have my blue lights, wig-wags, and strobes wired into 1 switch. I want to break that down into a 3 switch setup: 1 Master Switch (which will control blue lights all the time), 1 switch for the wig-wags (wig-wags only on when Master switch and wig-wag switch is on), and 1 for my strobes (same as wig-wag switch).....
Here is the SPST (i can get SPDT, DPST, or DPDT switches if need be) switch i will be using: (the Master switch ONLY will have a blue LED in the switch to show that the lights are on)
I would prefer to use relays to supply power to the lights.
Here is a diagram that i have drawn up to show the switch locations:

My best guess would be have the master switch be wired to do 2 things: 1:APPLY the 12v power to the relays for the wig wag and strobes (so now they can be activated by their respective switches by applying the power to their trigger) and
2:ACTIVATE the relay for the blues by applying the power to the trigger.

all the lights currently are ran off a 20A circuit......since all the blue lights are LED's total they draw only 6A....my wig-wags draw 5A and the strobes draw 5A.......the switchs that i am getting are rated at 20A....
how would i wire a relay for the lights? like what pin on the SPST relay would be for what?

Use the first relay, but power the wig-wag, and strobe switches from pin 87 on the relay.

On a SPDT with no current on the 85 pin, pin 30 and pin 87A from a circuit. When a current is applied to pin 85 pin 30 and pin 87 make a circuit so you couldn't use it that way. As for branching off the main switch to power the other switches there should be such a low draw across them it shouldn't matter. The setup I'm showing is using 3 plain switches and 3 relays to power everything. You could power the other 2 switches off of pin 87 depending on the amount of power you are pushing through. You would need switches rated high enough to handle the amps going through them. If you want to do that I can modify the diagram to show that.

Now there are DPST(Double Pole Single Throw) relays out there that will run 2 different circuits using only 1 coil to energize them.

Switch Part #: 0626
the SPDT relay that i have looks like this on the bottom and this diagram on top:

Oddly enough I cant find those listed on their website. But assuming that both the 87 power on at the same time you are right just power the other 2 switches from the secondary 87 pin. Again just make sure that the switches can handle the amps you are pushing though them. If the switches and relays are all one unit then the power for switches just goes into pin 85.
