DPDT Toggle Switch wiring for two fans
Posted: Thu May 10, 2018 9:47 am
Lets act like this is controlling two radiator fans for topics sake...(I'll delete this when I get it solved since its dealing with 110V, I just really need some help and you guys haven't let me down in the past)
So back story is this is a industrial hair dryer for a dog grooming setup, and its just two hefty fans hooked to a 110v socket via a dual pole dual throw toggle switch. The wiring shorted out and burnt the switch, along with the wire leads, so I couldn't just buy a switch and replace it. Had to cut new leads and the like. The dryer has two motors in it, and a "hi" and "low" setting with flipping the switch up or down. I figured one motor running would be low, and two motors running would be high (I may be completely wrong on this...maybe the fans are given different voltages somehow).
This is the drawing that I came up with to give one fan power with the switch down, and two fans power with the switch up. Does this make sense? I tried it last night and it didn't seem to work (now I'm thinking its cause I blocked the airflow intake)...but I feel like its wired correctly. I have 12/2 coming from the wall...so a white, green, and black. Each fan just has two black wires coming off them, one going to a brush on each side of the armature. Green is grounded on one of the fans.
