    Is it safe to trigger 2 relays (light bars) with a single switch? I'm thinking since the switch and relay side is low volt/amp then it shouldn't be a problem.

    Thoughts?

    You can get a double pole single throw (DPST) switch. It has two circuits linked to a single switch.

    100% safe to use either a DPST or SPST switch for simultaneously energizing coils on two separate relays.

    The #85/#86 pin relationship will not care how many others you’re playing with.
