    I picked up a spst pot by mistake. Is it possible to use this for a blower switch in a standard 3 way wiring for a tele with 1 vol 1 tone?
    If not, what are these pots used for generally?

    it depends on if it's normally open or normally closed, and if it switches at fully clockwise or at fully counterclockwise.

    That looks like a combination on/off switch and volume pot.

    I've used pots with the same combination of terminals as an on/off and volume control on Fender Champ style builds.

    Does it "click" off when it's turned all the way counter-clockwise?

    On a Champ,the two terminals on the back would be used to interrupt the AC power (line voltage hot wire).


    edit: If you have meter, connect to the two terminals on the back. If you have continuity with the switch turned clockwise, and then lose continuity with the switch turned fully counter-clockwise, I'd swag it's it's an on/off - volume (or tone if desired) type pot.




    Best Regards,

    No, it is a push pull switch, it only has 2 terminals instead of 6. Hence single pull single throw(I think)
    So it can def be used to split a humbucker , just not sure past that.
    I would like to use it for a blower switch(straight to amp)

    You would be awfully close to that if you took the grounded lugs of the volume and tone pots and instead of grounding them directly, connected them together, ran that to the switch with the other end of the switch grounded. When the end of the volume pot is not grounded it makes very little difference if it is turned up or down, and if it is turned up it is just like straight through. When the tone pot is not grounded it does nothing at all.

    I can't tell you if it would be more likely to hum when activated....

    (If the tone capacitor has one end grounded, use that grounded end instead of what I called "the grounded end of the tone pot" up in the first sentence.)

    A blower switch requires a DPDT switch.

    No, what tessting said. Requires a DPDT.
