“Draw a 5 V TTP223 touch switch circuit with a 100 nF capacitor, 10 kΩ gate pull-down resistor, MOSFET, and LED strip load.”
그렇다면Change the LED strip to a 12 V load.Add a power switch.

01
Use N-channel MOSFET low-side switching so the gate can be driven directly from the TTP223's 5V output
02
Add 10k pull-down resistor on the gate to keep the LED strip off during power-up or no-touch
03
Place 100nF decoupling capacitor across TTP223 VCC for stable touch detection
Reuse for any capacitive touch toggle switch controlling low-power LED strips or small DC loads from a 5V sensor output.
