LW26 Series (Change-over Switch)

The LW26 series universal change-over switch is suitable for AC circuits with a frequency of 50Hz, a rated operational voltage of 690V or lower, and DC circuits with a voltage of 240V or lower. It can handle a rated current of up to 100A and is designed for infrequent manual connection and disconnection of circuits.
Additionally, it can directly control small-capacity AC motors and be used for circuit measurement. The LW26 series switch offers several advantages, including a compact structure, multiple functions, an attractive design, good insulation properties, flexible operation, and enhanced safety.
