As shown in the diagram, SM is a change-over switch which is also known as combination switch, and the common models inlcudeHZ10, HZ15 series. It has a rotary handleto drive three movable contact pieces rotating at the same time and turn ON or OFF respectively the three pairs of stationary contact pieces.When it isturned on, the motor starts rotating; when it is cut off, the motor M stopsrotating. The circuit isused for the grinders, lathes and other mechanical equipments.
