Edwards Signaling 45 Rolling Ball Contactors

Honestly the worst ball contact ever. It constantly getting stuck in closed position. Not a great if you are using this for alarm system.

Make sure you get the version correct. There’s normally open or normally closed. The description on Amazon is not great so go to Edwards to make sure get what you need. I had to send mine back and get it corrected.

Product seems OK…replacing another one that made contact intermittently without rime or reason.Consequently, I cannot advise if this one will have same problem. Be advised….this is for low voltage only !Make sure your relay matches this switch or you might find your light goes off when you want it to go on.

fast service. Exactly what I needed to replace the one originally installed 30 years ago. I hope this one lasts as long.
