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.
