These are the ones Im talking about

Yup, we are on the same page.

They are SCR or TRIAC controlled. A TRIAC is just two SCRs wired in reverse parallel.

As long as the gate is energized, they continue to conduct.

The circuit connected to the gate determines if and when they conduct. They connect the resistor/capacitor circuit to the gate to create a timer.

If the circuit is a time on break circuit they use an intergrated circuit as a relay to reverse the process. Thus they can create them to open on delay or close on delay, your choice.

Ok, thanks. Im getting the duct tape for my head now.

Silly putty works for me!

klixon type resistor for a r/o switch, anyone can explain the function between the reading of having resistance reading on ohms, and a zero reading? and why its good if its zero, but not if it has a resistance reading?

and lingo, i just got in a hurry and didnt read, and yes, that solid state would be the board that gets the burnt mark that is down the line from the tdr, cool!
so much for pot relays, same theory , just modified, and a different application,,, as to the back emf
