It's not an electical wiring problem I have, but rather finding the right switch! What is the 6th post for on a 6-post on-off-on toggle switch? I need a replacement, but there is slim pickings on 6-post illuminated switches. Besides the one I found here, are there any other good stores to find these switches? I need one that is brushed aluminum red led. What a pain... Larson wants to charge near $50 for a $10 switch.
