Application

Class 12 manual starting switches are designed to economically start and stop inherently protected single and polyphase motors as used in light machine tools, pumps, blowers, and vent-fans. They are also used as ON and OFF switches for resistive loads such as heating.

Features

This switch is compact, economical, and easily wired using pressure type screw connectors. A rugged over center toggle mechanism results in a long life with weld free operation. It is available for sur- face mounting in a NEMA 1 enclosure, for flush mounting on a standard depth switch box or in custom panels. A pilot light for 120, 208 / 240, or 480 volts may

be added at any time before or after installation.
