Instructables

I have this thing?

I have this thing. I got it from a bag of  obsolete parts where my dad works. It's a component, with a black plastic body.

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:

AMF
POTTER & BRUMFIELD
109P471
JRE-4011
MADE IN U.S.A.               (Out here it has a symbol like "SA" inside the letter C)
02-07-75

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.

Steve is correct it Is a relay DPST.

2 pins are the coil and 3 pins are the Single Pole Double Throw switch.
See the pic.

Can I assume that the uneven pin spacing is meant to denote which of the contacts is NO?

Usually YES..

IF you have an ohm meter then ;
The two pins that are not zero but several to hundreds of ohms are the coil.
Then you need to start with 5vdc 12vdc 24vdc to find working voltage.
then you can find the contacts start with the zero ohm first..

I think it might be a SSR though. I was breadboarding it earlier today, and I noticed that the contacts were polarized: current could only flow through in one direction. Also, powering the "coil" only connected two of the contacts to each other. The third one just... sits there like a chump. I don't know, I might be doing something wrong.

You might be correct your partial blur pic does have the outline of an SSR.

Looking through a PB catalog no luck finding that shape.

Blame a 2.3 Mp cameraphone and critically shaky hands.

My hand trembles too.

That's why I made an iPhone saddle to help my pics :-)

I don't really know, but when I played with it yesterday it did make a slight click when I activated it. I have to test it with a multimeter when I get home.
You know the expression, " a picture is worth a thousand words"

Actually, never mind.

The pins on the left are spaced unevenly, the center pin is closer to the top than the bottom.

I would have posted a picture, but I'm at school and using one of their cardboard netbooks.
