Use a variable resistor (potentiometer / rheostat) symbol — i.e. a resistor with a movable wiper — to show a fan speed control.
Of your three descriptions:
- The first one (short line, circle, short slanted line/wiper, gap, circle, short line) is the intended idea if it’s meant to show a wiper/slider on the element (so choose this if it really represents an adjustable contact).
- The third is just a fixed resistor and isn’t correct for an adjustable control.
- The circle with an X is a lamp symbol, not a fan controller.
If the controller is electronic (triac/PWM module) it’s better to show the motor symbol with a labeled "speed controller" box or the actual triac/transistor circuit next to it, rather than a simple potentiometer symbol.
