Famous Cable Connector Lugs Supplier – LW26 Series Rotary Changeover Switch – Changan Group

Introduction

The LW26 sereies rotary switch mainly applies to 440V and below,AC 50Hz or 240V and below DC circuits. For breaking and closing, change-over of circuits under unfrequently manual operation. And the typical application are: control switch of 3 phase motors, control switch of switch gear, control switch of instruments,and change-over switch of machinery and welding machine.
The series comply with the IEC 60947-3,IEC 60947-5-1.
The LW26 series have 8 current ratings:10A,20A, 25A,32A,63A, 125A,160A and 315A.
The LW26 series rotary switch were designed for multiple functions, wide variety of applications.
The LW26-10,LW26-20,LW26-25 ,and LW26-32F have finger protection terminals.
Both of them are applicable in circuits when an physical control is required.
We can equip protective box for 20A,25A,32A and 63A. .
