    Looking for an old school (discrete component) simple stable 't' flip flop circuit to mimic alternate action (push-on push-off) with a momentary switch.

    Any ideas?

    Good site Bertus, but I need a single input which would toggle an output.
    Thanks Michael

    OK, I assume no integrated circuits. Why? You can buy flip flops in the chip, the only difference between a IC and one made with transistors is parts count.

    I've seen them, built them, but never saved any schematics because dual flip flops are so cheap and easy.

    Here is a circuit I made long time ago.
    Hope it helps.

    Should be a attachment somewhere on here.
    If I uploaded it right.

    Here is a discrete "alternate action" circuit.

    Interesting. I had a little trouble seeing the set/reset flip flip embedded, but it's there. Have you seen this circuit work Guru? I'm thinking of the up and coming cookbook.
