LW2620 Rotary Switch Knob — 2position 01 ONOFF changeover cam A straightforward, reliable rotary switch designed for clear ONOFF control in electrical panels and equipment. The LW2620 provides positive changeover switching with a compact 2position cam and wiring flexibility for straightforward installation and service. Key benefits Simple, intuitive control: 2position 01 ONOFF action gives unambiguous on/off operation for a single circuit. Rated for demanding installations: Ui 690V and Ith 20A allow use in many industrial and commercial electrical systems. Wiring flexibility: 4 terminal design supports feedthrough or looped connections and simplifies replacement or rewiring. Positive mechanical action: changeover cam provides reliable contact transition to reduce contact bounce and improve switching consistency. Singlepole control: isolates one circuit while minimizing footprint and wiring complexity. Key attributes Model: LW2620 Function: Rotary switch knob, 2position (01), ONOFF changeover cam Rated insulation voltage (Ui): 690V Rated thermal current (Ith): 20A Poles: 1 pole Terminals: 4 terminals Operation: Manual rotary actuation with defined ON and OFF positions Typical applications Control panels and distribution boxes: use LW2620 as a compact on/off selector for individual circuits, auxiliary systems, or control circuits. Machinery and equipment isolation: provide a clear manual disconnect or control point for maintenance and testing of singlephase or singlecircuit loads up to the rated voltage and current. Test benches and service stations: implement as a simple, robust selector for powering test circuits or switching instrumentation on and off during diagnostics. Installation and safety notes Verify that the switch ratings (Ui 690V, Ith 20A) match or exceed the requirements of your application before installation. The 4terminal layout allows feedthrough or separate feed/load connections; follow wiring diagrams appropriate to your panel or equipment. Always isolate power before wiring or servicing the switch and comply with applicable electrical codes and safety practices. The LW2620 provides a nononsense, robust solution for singlepole ONOFF switching where clear operation, rated performance, and simple wiring are required.
