Overview
The Square D 2510-KO Type K manual switch is a non-reversing motor control device designed for manual ON/OFF operation of AC motors up to 600 VAC. Part of the proven 2510 series, this switch delivers reliable motor control in applications where overload protection is not required or is provided separately. The open-type construction fits standard single-gang switch boxes, making it suitable for both wall-mounted and machine-mounted installations.
