[QUOTE="the doctor, post: 316903, member: 75"] Hello all, I attended a shower fault the other evening. The house had two showers off one supply on a relay. One of the components was....... All I can do is describe it here as I have never seen one. Looks like a din rail mounted relay with a couple of auxiliary contacts. The unit was marked 7-39A. When the shower was turned on that was supplied through the unit the auxiliary terminals went open circuit. It looks like some sort of reed switch that is triggered by the current passing through it I have been on many jobs my whole life and feel humbled by this one. When I figured out howit was wired I seen it was simple yet clever! Can the forum tell me, what it is called and where would you use them Cheers [/QUOTE]
