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 have 8 current ratings: 10A, 20A, 25A, 32A, 40A, 63A( 125A, 160A,250A, and 315A. They were designed for multiple functions, wide variety of applications.The LW26-10; LW26-20, LW26-25, LW26-32F, LW26-40F and LW26-63F have finger protection terminals.

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.
