[It was a] normal pattern to a base leg. After deploying flaps; the boost pump was accidentally switched on; which flooded the engine and caused a total loss of engine power. Due to the low altitude and the flaps being fully deployed; the aircraft could not glide to the runway; so I made the decision to take control and land off to the left side just short of the runway. The aircraft stopped rolling approximately 25 feet before the runway threshold. There appears to be no damage to the area where the landing occurred or to the aircraft itself. There is no sign of mechanical failure; only pilot error.
A36TN Bonanza pilot reported accidentally switching on the boost pump causing an engine failure at low altitude; resulting in an off-runway landing.
