I'm building a control circuit for switching the VFD on my lathe. The latching push button circuit needs to use two momentary push buttons one for on one for off. I got a circuit working with a double throw relay however the VFD switch circuit couldn't supply sufficient current to hold it on.
My hope is to use transistors as they should draw less current when operating.
Dave Jones on the EEVblog did a video on a soft latching push button circuit however his final design uses just one button. He briefly goes over a circuit using two buttons however i can't get this to work. He hasn't out any resistor values on it and I don't understand the circuit well enough to work it out.
to summarise: What are the resistor values for this circuit to get it working.
If somebody could help that'd be fantastic.
