Does anyone know about or have ever seen low voltage lighting system in a 40 year old house original to the house?
I was called out to a house to trouble shoot a lighting circuit and found it to be a low voltage switch circuit.
The switches are momintary contact push buttons.
And the relays are plunger type relays.
The plunger moves a cam when energized and the cam turns and closes the circuit.When the plunger is energized again it turns the cam again opens the circuit.
I have called all my supliers and they have never heard of such a thing.
There is no name or numbers on any of this equipment.
