    DMCH on off console switch

    Has anyone used one of these on/ off switches from DMCH? Part#111638. Does any one have a pic of the terminal side? Also is it a SPDT switch?? Thanks!

    Probably the same as a defrost switch without the graphic.
    My window switches had the graphic wearing off so I replaced them with the led ones. I was going to use the old ones in tbe dummy spots and tie them into my door launcher actuators (would make it easy for me to open the passenger door from inside the car). I thought better of it since I rarely lock the doors and was afraid I would accidently trip it while driving.

    The reason I am asking is because I am looking at sending my craig radio to Dimitri for the Bluetooth mod. There is a switch that is pigtailed on the radio that is used to turn the Bluetooth on and off. But I like to keep things looking stock so I thought if I wired it to one of the rocker switches DMCH sells to replace the blanks that would be perfect. But I have been told it needs to be a SPDT switch or a “single Pole Double Throw” type.
    The other idea I had was to use this switch with a relay that is SPDT. And have the relay switching or toggling the Bluetooth function.

    Hope this helps. Use the two out side connections for simple on/off. I'm using one for my flux capacitor.

    Awesome thank you! Do you by chance know what the center lead is for?

    DMCH says it is a "simple "on-off" switch", so it is a SPST.
    They allow you to connect or disconnect two terminals.

    A SPDT allows you to choose one of two terminals to connect to a 3rd, ie "either/or".

    If the pigtailed switch only turns the Bluetooth on and off, it sounds like the DMCH switch would work to me. I'd run this by Dimitri to be sure w/o a schematic.

    I also use one of these switches to turn a Bluetooth adapter on and off. I don't recall the pinout, but I was able to use this as a simple power cutoff for my Bluetooth adapter. If I remember correctly when I hooked up the multimeter to the switch I realized I could use 1 pin for power in and the other two would have worked equally well going out so I just picked one at random.

    I'm happy with the switch!

    The center lead is used on the defrost switch to activate the "Rear Defrost" light on the console.

    According to Dimitri it needs to be a SPDT switch

    If I understand it correctly the pigtailed switch , switches between radio and Bluetooth.
