I have this thing?
It's about 24 mm wide and 19 mm long. It has five leads, two coming out of the right and three coming out of the left.
The text on it is as follows:
POTTER & BRUMFIELD
MADE IN U.S.A. (Out here it has a symbol like "SA" inside the letter C)
The last one is obviously a date, it was made in the seventies. AMF used to make all kinds of things in the 60's and 70's apparently, so this must just be one of their products. My dad and I think it's a relay, but I've Googled it to no avail. Are there any old-time electronics nuts who can help me out here? Thanks a lot.
