This shouldn’t happen in theory in a properly engineered and built system. The switches have arc chutes inside of them already, and the contacts are spring loaded to open and close as fast as possible to minimize. On the motor end, the maximum amount of amperage a motor pulls is called the Locked Rotor Current. You can achieve LRC by stopping a running motor with a screwdriver. But a motor also hits LRC for a brief second every time it starts from a rest state. So a UL rated motor sees maximum amperage all the time in its normal lifecycle.
