Introduction
HW26 series rotary switches are suitable for:on-off of electrical circuit,change over of electrical circuit motor switch,instrument switch,and main switch.
HW26 series rotary switches comply with:IEC60947-5-1.
HW26 series rotary switches have six current ratings :20A,25A,32A,63A,125A,and 160A.HW26-20 and
HW26-25 have the fingerproof terminals,which offer an extra advantage.

Working Conditions
1)Ambient temperature do not exceed 40oC,and the average temperature,measured over a period of 24 hours ,do not exceed 35oC.
2)Ambient temperature do not be less than -5oC.
3)Should not be installed above 2000m and above sea level.
4)A clean environment is required.
