Sounds like you want a SPDT ON-ON

Cheers,

Subject: SPDT or DPDT switch?

Hi folks:

Just a quick question about switches: I need a switch that when toggled in
one position will operates one appliance, and when toggled in the other
position will operates a second, different appliance. Do I need a single
pole double throw switch, or a double pole, double throw switch? I'm
guessing the latter, but wanted to doublecheck. The SPDT would operate two
appliances at the same time then presumably vs a SPST? Just a bit confused
here on how these work.

Thanks,

Troy
