[Boatanchors] Re: GB> Solid State Relay Question

[Richard Post]

Hi Greg,

Such relays are commonly used in microwave ovens which cycle the 
final power to the main transformer for reduced cooking levels such 
as defrost. (You can see the action when the timer kicks in full 
power for a few seconds at a time by noting the slightly reduced 
light from the oven light bulb each time the circuit is loaded.)

A dead microwave oven may provide all the recycled pieces with enough 
capacity needed for your circuit.
