Voltmeter Off-RN-SN-TN-TR-ST-RS Three Poles 20A 7 Position Rotary Cam Switch Interruptor LW26-20YH5/3 CA10

The LW26-20YH5/3 Rotary Cam Switch is a heavy-duty 7-position voltmeter selector switch designed for precise voltage measurement across multiple three-phase circuit combinations. With clearly labeled positions — OFF, RN, SN, TN, TR, ST, and RS — this switch makes it easy to monitor line-to-line and line-to-neutral voltages in a single compact unit. Built with three poles and a 20A current rating, it is well-suited for industrial control panels, switchboards, and test benches. The cam-driven contact mechanism delivers accurate and reliable circuit selection with every rotation. Terminal connections are clearly numbered for straightforward wiring, and the panel-mount design allows for seamless integration into electrical enclosures. Rated at up to 660V insulation voltage and compliant with IEC 60947-3 and GB/T14048.5 standards, this switch is a dependable choice for demanding electrical measurement applications.
