Can anybody help me make a PCB for 24V 5A capacitive 3-state touch switch from the attached curcuit diagram ? This is for a Bluetooth loudspeaker with light. Uses P channel MOFETs. The 4017 is configured to reset on count #3. Standby current is appx 200 micro amps.touch switch.png

Before you build a PCB, you may want to at least run a simulation of the circuit using LTSpice or some other spice tool and or test it on a solderless breadboard, especially the touch plate idea.
