LW5D16/YH3.3 16A Yellow Panel 4 Position 3 Pole 12 Screw ThreePhase Voltmeter Rotary Changeover Cam Switch Overview The LW5D16/YH3.3 is a panel mounted rotary cam switch designed for three phase voltmeter applications. It provides 3 poles and 4 positions, with a 12 screw terminal block for wiring, and a current rating of 16A. The yellow panel face enhances visibility in control panels, helping operators identify the switch easily during setup and maintenance. Key benefits Simplified three phase voltmeter wiring: a compact 3 pole, 4 position cam switch that routes voltmeter circuits across multiple configurations without rewiring. Reliable manual operation: rotary changeover action enables precise, repeatable switching between different measurement or wiring paths. visibility and clear identification: yellow panel improves legibility in busy control panels and enclosures. Flexible wiring options: 12 screw terminals provide convenient and tidy connection for complex three phase wiring schemes. Panel mounted for durable in situ use: designed to fit standard panel cutouts and installations in electrical and control cabinets. Key attributes Model: LW5D16/YH3.3 Current rating: 16A Poles: 3 Positions: 4 Terminals: 12 screws Panel color: Yellow Mounting: Panel mounted Application: Threephase voltmeter rotary changeover cam switch The specification set supports switching and routing of voltmeter connections in threephase systems with a four position configuration Notes on specifications The information reflects the model, current rating, pole and position count, terminal count, panel color, mounting style, and intended use as a voltmeter rotary changeover cam switch for threephase applications. Voltage rating, insulation, material construction, IP rating, and other electrical specifications are not provided in the product title and should be confirmed with the supplier or product datasheet before installation. Use cases Threephase panel monitoring: Use the switch to select among different voltmeter inputs (for example switching between phasetophase or phasetoneutral measurements) in a control panel. Equipment testing and calibration: On a test bench, utilize the four positions to route the voltmeter to multiple reference points or test points without rewiring. Industrial control cabinets: Employ the switch to quickly reconfigure measurement circuits during commissioning, maintenance, or diagnostics while maintaining a single, accessible control element. The LW5D16/YH3.3 is suitable for installation in electrical control panels where a robust, clearly visible, panel mounted cam switch is required to manage voltmeter connections in a threephase environment.
