I would like to see if possible to use a mosfet like the irfz44n to do the job as a touch switch... off-course it will need a few more components, but my drawing has the general idea. the lamp already build and works well. just need to add the touch switch. I would like the touch switch works with the 20vdc psu directly for simplicity and space constraint. I got the idea watching a brief segment of this video at 58 sec mark, it touches the gate with his finger and turn on and off the light, but i am sure it with need more than that in order to make it more reliable. https://www.youtube.com/watch?v=o4_NeqlJgOs thanks
