LW1216/YH3.3 16A 4 Position Pole 12 Screws ThreePhase Voltmeter Conversion Cam Rotary Switch The LW1216/YH3.3 is a fourpole, fourposition cam rotary switch designed for threephase voltmeter conversion. It is rated to handle up to 16A and provides 12 screw terminals for flexible wiring and reliable circuit routing. The camdriven switching mechanism delivers precise, repeatable position changes, making it suitable for measurement and control applications in electrical panels and instrumentation setups. Key benefits Enables reliable switching of threephase voltmeter circuits with a compact, multipole design. Fourposition, fourpole configuration supports multiple measurement paths or voltmeter configurations in a single switch. 12 screw terminals offer ample wiring flexibility for complex threephase connections. Cam rotary mechanism provides precise, repeatable positions for accurate instrumentation routing. 16A current rating supports typical utility and controlpanel measurement use without oversizing the switch. Key attributes Model: LW1216/YH3.3 Type: Cam rotary switch Poles: 4 Positions: 4 Terminals: 12 screws Current rating: 16A Application: Threephase voltmeter conversion Construction notes: Exact material and enclosure details are not specified in this description; designed for panelmounted, measurementoriented switching in electrical control and instrumentation environments. Compatibility and performance Suitable for integration into threephase measurement circuits where multiple voltmeter configurations must be selected or routed. Appropriate for control panels, instrumentation cabinets, and testing setups requiring multiple quickswitch connections with a single device. The 4pole, 4position arrangement accommodates complex wiring schemes while maintaining a compact footprint. Use cases Use case 1: In a threephase motor control panel, configure and switch between different voltmeter measurement paths to monitor phase voltages during maintenance or startup sequencing. Use case 2: In a test bench, route threephase signals to separate voltmeters or instrumentation channels for comparative voltage analysis across multiple configurations. Use case 3: In an industrial automation panel, enable quick reconfiguration of measurement circuits for calibration, diagnostics, or commissioning without rewiring. Notes This description reflects the model LW1216/YH3.3 with a 16A rating, 4 poles, 4 positions, and 12 screw terminals designed for threephase voltmeter conversion. Specific voltage ratings, material composition, and enclosure dimensions should be verified in the product's detailed specifications before or integration.
