5-10 years ago, the PIR motion sensors on the market had 3-wires, basically
HOT and Nuetral feeding it's electronics, and a LOAD wire exiting the switch
which was used to attach the controlled device and acted as a switched HOT.
NOW, I find that EVERY PIR switch I've seen on the market seems to be a
TWO-wire version. This is great for higher current loads, but low current
loads (like a 4watt bulb) do not provide enough current flow to make the PIR
circuit operate reliably.
Does aanyone know of any brand of PIR that still uses 3-WIREs?
