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 unfrequenly manual operation.And the typical application are:control switch of 3 phase motors,control switch gear,control switch of instruments,and change-over switch of machinery and welding machine.
The series comply with the GB 14048.3,GB 14048.5 and IEC 60947-3,IEC 60947-5-1.
The LW26 series have 7 current ratings:10A,20A,25A,32A,63A,125A and 160A.
The LW26 series rotary switch were designed for multiple functions,wide variety of appli -cations.
The LW26-10,LW26-20,LW26-25,and LW26-32F have finger protection terminals.
LW26 series rotary switch are an excellent substitute for LW2,LW5,LW6,LW8,LW12,LW15,HZ5, HZ10,and HZ12.
The LW26 series rotary switch has two derivatives,LW26GS Pad-lock and LW26S lock.
Both of them are applicable in circuits when an physical control is required.
We can equip protective box for 20A,25A,32A and 63A.

Designation
Use as control switches

Re: Character code represent the rotating type, for instance, we have limited movement, spring return and limited movement with spring return.

Use as motor switch

Re: switches in this category normally rotate at 60°. And the SN normally rotate at 45°

Use as control switch for a main circuit

Re: switches in this category normally rotate at 60°
