The scenario
Design a pump control system for a sump pit that automatically turns on when water rises, with manual override for maintenance.
What is in this drawing
Read the decisions behind it.
01
Chose MOSFET over relay for solid-state switching
02
Included flyback diode for inductive kickback protection
03
Used pull-down resistor to prevent floating gate
Use when a simple DC pump control with manual override is needed for small liquid management systems.
