The LW26 series rotary switch mainly applies to 440V and below, AC 50Hz or 240V and below DC circuits. It is designed for breaking and closing, and change-over of circuits under infrequent manual operation.
Typical applications include: control switches for 3 phase motors, control switchgears, instrument control switches, and change-over switches for machinery and welding machines.
The series complies with GB 14048.3, GB 14048.5, IEC 60947-3, and IEC 60947-5-1. The LW26 series features 10 current ratings: 10A, 20A, 25A, 32A, 40A, 63A, 125A, 160A, 250A, and 315A. They are designed for multiple functions and a wide variety of applications.
The LW26-10, LW26-20, LW26-25, LW26-32F, LW26-40F, and LW-60F models feature finger protection terminals. The LW26 series rotary switches serve as excellent substitutes for LW2, LW5, LW6, LW8, LW12, LW15, HZ5, HZ10, and HZ12.
The LW26 series rotary switch offers two derivative types: the LW26GS Pad-lock type and the LW26S Key-lock type. Both are applicable in circuits where physical control is required. Protective boxes (IP65) can also be equipped for models ranging from 20A to 250A.
2. Working Conditions

Please follow the provided manual.
4. Order Procedure
When placing an order, please specify the contact diagram of the product you require. The LW26 series rotary switches feature similar contact diagrams to other rotary switches such as LW2D, LW5D, LW6D, LW8D, LW12, LW15, HZ5D, and HZ25D. Reference to the General Contact Diagram for Rotary Switches will assist you in specifying the correct layout.
Additionally, please specify the current rating, mounting plate, handle type, color, and quantity.
For instance: When ordering 20A, rotary angle 60°, character code C, contact diagram code 5391, M1 plate, black R handle, 20 units. The order can be written as: LW26-20.6C5391/2A11R(M1R) 20 units.
Due to continuous technical updates, the specifications in the catalogue are subject to change without prior notice.
