The products pose a risk of fire because during very heavy use or when the motor is stalled, the internal switch contacts become hot causing the case to melt in the vicinity of the switch. There is no thermal trip to cut the load to the switch in stall/high load conditions. In extreme situations the casing can catch fire.
