These contacts also may be shown as a drawing of a line from 1 contact ending in a dot the nc contact and another line from another contact that is near the dot but. For instance the following diagram shows a normally open pushbutton switch controlling a lamp on a 120 volt ac circuit the hot and neutral poles of the ac power source labeled l1 and l2 respectively. A 600 p 300. Iec contactors 41 42 iec contactors and auxiliary contact blocks 41. Use these tips to learn how to wire a contactor. We will use a contactor an auxiliary contact block an overload relay a normally open start pushbutton a normally closed stop pushbutton and a power supply with a fuse.
