Old GE hood vent. The push button light switch is broken. Had two on settings dim and bright. Pulled the switch and it has three wires. Blue Black and Orange. Local hardware store just has a simple push on, push off switch with two black wires. Don't know but are there three wires because of two different on settings? Really just need to turn on(bright) and off. Any way to use the two wire switch to do this? Thanks for any help.
