641-Series 641-Series PUSHBUTTON SWITCHES The single, double and triple pole 641-Series represents the most compact offerings of the Carlings pushbutton switch line. These switches are UL approved and meet ENEC spacing requirements. Additionally, the new 3-pole switch affords the versatility to control an extra function or indicator light. Rugged metal construction, self-cleaning contacts and stiff actuation force (3-3 1/2 lbs. typical) have made these switches ideal for most foot pedal type applications. These alternate action switches fit a standard .500 mounting hole with options of solder lug, wire lead and PC terminals.
