Electronic Load PWM MosFET

Rotary Switch 5 positions 1 pole (thanks Multisim for not having it in parts), selects 1, 2, 3, 4 or 5A current on MosFET. This circuit is to force current compsumption from a power supply, power dissipates over the Power MosFET. LED1 indicates when there is at least 500mA of current. Can't include power switch and indicator since Multisim blocks this quantity of parts.
