Okay, I’ve been doing this awhile now.  And quite often run into the situation below: Kitchen sink with a light over it and two switches next to the sink.

Kitchen Switches
Kitchen Switches

One switch operates the light, the other operates the garbage disposal.  I’ve had builders and electricians alike both tell me that the switch closest to the sink operates the disposal.

No.  Not even close.  I don’t think my score is even close to 50/50 because I always try the switch farthest away but am usually startled by the garbage disposal going.

On the days I get it right I buy a lottery ticket.

So, if you’re an electrician and install this so that A is the light and B is the disposal, thank you.

If you do it the other way around, you’re an asshole.
