Hello folks, I am looking for some help. I have a customer with a range hood that has a bad switch. The switch is a 3 wire 4 position rotary switch. The positions are 1-load #1, 2-load #2, 3-load #1&2, 4- off.This switch is approx 1 inch square, about 3/8 thick. I thought it was going to be easy to replace until I tried to find one. The range hood manufacturer has gone under and there are few legible markings on the switch. I have exhausted my usual sources of these types of oddities. I can find it in pull chain but rotary seems to be more difficult. I was wondering if anyone has any info on a source for a switch like this.ThanksDave
