    Sorry for confusion, it was late

    Original is rated 10A 125v (no mention of AC or DC from memory). The new one is rated 6A 125v (again no mention of AC or DC).

    I guess the voltage is the giveaway.. Seems to be the switch Brian is using & they are cheap so if it goes I'll replace it. As you say trial & error.

    Not sure I can be bothered to wire in 2 relays (it has 2 circuits (heaters have 3 wires) for hi low so only way I can see being able to switch the relay is to switch 1 relay for each circuit.

    It'll be fine, really.

    The biggest problem is how to solder the wires onto those teensy-tiny mini terminals on the back of that wee little switch. You need beady eyes, nerves of steel, and steady hands.

    Here's a really crappy pic of the switch on my VX800 -- the switch on my GS850 is mounted the same way. It's a simple tab of stainless steel (crudely pounded flat and painted black) with a 1/4" hole at each end. You can sort of see that the switch body is covered with shrink tubing for a nice clean look and weather resistance.

    Thanks! think I have room on my custom ignition \gauge plate on this one although your idea really puts it at hand so maybe I'll go with that.

    I haven't put a lot of time into it yet but I'm wondering if there is a way to get the relay to do the bulk of the switching work rather than running the full load through the switch. The switch that came with it is huge & I have picked up a much smaller one from "the shack" DPDT Mini Toggle but it's only rated at 6A (125v) rather than 10A (125v). The switch is a 3 position for "hi / low".

    The only obvious way I can think of involves using two relays....

    Cheers,

    Old thread, but occasionally someone runs across them and may need a diagram. Since there was not one posted I thought I'd help out. I had a two-speed fan relay setup in a V8 RX-7 that was very similar.. and very easy to modify the diagram. This uses a three position switch low/off/high.
    Two automotive SPDT type relays:


    Assumptions-
    12 volts comes into the switch.
    If off, it goes nowhere.
    If low, high is not energized and it energizes the low relay coil and sends the load to the low input of the heater.
    If high, low is not energized and it energizes the high relay coil and sends the load to the high input of the heater.

    I actually wired them like this



    BW is a ground. I actually picked up the orange wire in the rear light bundle as a switching wire from memory.

    2nd relay wasn't necessary as the switch can handle even the high current fine.
    For something more powerful a 2nd relay would protect the switch though. Good diagram.
