Here's an update with photos of the innards.
I think there might be a way to rewire this one, but it would require
cutting part of the switch. Not sure about that... Right now it's shaped
like an "S" when not depressed:
---- (white wire connects here)
{
---
}
---- (black wire connects here)
When the pedal is depressed, it looks more like this:
---- (white wire connects here)
---
/ }
---- (black wire connects here)
So, the switch is open. See the photos here.
