Basic flow switch question.

I can. They are actually the same size - just an illusion from the pic. Just disappointing the quality of things today.

Great you got it figured out.

Some observations on the pic yo0u posted.

The plug on the right that worked has four contacts although only two are used.

The two plugs on the left only have two contacts.

Are those two plugs on the left genuine Hayward parts or aftermarket from Amazon?

Plug on left was the one that worked. It wasn't original hayward as I replaced the flow switch about 10 years ago. The two on the right are aftermarket also. Don't have the Haywood switch pictured. Left it at work as that's where I got it tested. Its getting returned.

Eventhough the one on the right has 4 contacts but there are only two wires in the cord.

I think aftermarket parts were higher quality 10 years ago.

You just confirm why I discourage the use of aftermarket parts from Amazon. To me they are more trouble then they save when they don't work.
