Application

The LW26 series 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 infrequently 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 GB 14048.3, GB 14048.5 and IEC 60947-3,IEC 60947-5-1. 

The LW26 series rotary switch has two derivatives: LW26GS Pad-lock type and LW26SKey-lock type. Both of them are applicable in circuits when an physical control is required.


Working Conditions

(1) Ambient temperature DO NOT exceed 40℃. and the average temperature, measured over a period of 24 hours. DO NOT exceed 35℃.

(2) Ambient temperature should not be below -25℃.

(3) Should not be installed above 2000m above sea level.

(4) The humidity should not exceed 50% when the ambient temperature is 40℃ and higher humidity is allowed for lower temperature.
