Transistor MOSFET (pMOS)

Schematic symbol

P-channel MOSFET: turns on when the gate (G) is pulled several volts below the source (S). Typically used as a high-side switch, source to the positive supply and load between drain and ground, for example to switch power to a whole circuit. Add a pull-up resistor from gate to source so it stays off by default. Learn how transistors work
