# What happens when an electrical load is supplied to a motor via a switch and the motor doesn't turn?

I'm not from an electrical engineering background. But I'd like to understand what happens when I have the following: Electrical 'main power' switch ------> 'small switch' ------> electrical motor

In this case, when both switches are ON but the electrical motor is faulty (it doesn't turn, just buzzes) what is happening to the electrical load (if that's the correct term). I expected the electrical motor to start smoking in this scenario but it was the 'small switch' that got fried. The 'small switch' had an Input voltage of AC 90-250V 50/60 Hz and a Max. load: 10 amp. Neither of which would be exceeded by the 'main power' switch.

• What was the voltage and current rating of the power supply? For instance, if the power came from a mains wall outlet, how much current can that outlet provide? Commented Jun 24, 2021 at 2:37
• Probably a large current is flowing into the motor. Large enough to kill your small switch but not large enough to kill your large switch. Commented Jun 24, 2021 at 2:40
• the motor is the electrical load Commented Jun 24, 2021 at 3:03
