## Overview

The Baomain SZW26-20/D202.2D-W is a robust 3-position rotary changeover switch rated for 660V and 20A, designed for manual motor reversing and generator transfer applications. Featuring premium silver alloy contacts and a flame-retardant IP65-rated enclosure, it ensures safe, efficient power switching. Its wider box design and included wiring map make installation straightforward, ideal for both industrial and advanced DIY setups.

## Description

Versatile 3-Position Control: Features a clear 1-0-2 (ON-OFF-ON) indexing mechanism with 8 terminals. Specifically designed for manual motor reversing and generator transfer systems, ensuring safe and synchronized circuit switching for industrial or DIY projects. Premium Silver Alloy & Installation Tip: Equipped with high-conductivity silver alloy contact points for efficient power transmission. Pro Tip for Safety: To prevent localized overheating and potential melting, please ensure all screw terminals are tightened firmly during setup; loose connections significantly increase electrical resistance and are the leading cause of heat buildup. Industrial Grade Specifications: Rated for a 660V Insulation Voltage (Ui) and a 20A Thermal Current (Ith). The housing is constructed from reinforced flame-retardant PC material, providing excellent heat resistance and ensuring high-temperature insulation safety under standard operating conditions. Wider Enclosure & Wiring Suggestion: The "Wider Box" design (3.15" x 3.15" x 3.7") provides more internal room than standard compact versions. Note: For the best experience and to prevent terminal strain, we highly recommend using flexible stranded wires (14-12 AWG) instead of rigid solid cables. Visual Wiring Map Included: This 8-terminal configuration supports 2-phase control. We have provided a detailed Truth Table (Wiring Logic Map) in the product images to guide you through the terminal connections and ensure successful continuity.

Review: Easy to wire and use. - Worked as required and easy to connect wires. Would recommend.
Review: Deviatore elettrico di buona qualità - Da un’azienda specializzata nella produzione di componenti elettrici, ecco un interruttore universale che può trovare largo impiego nell’uso domestico e nell’attività professionale. Si avvale di tre posizioni per deviare la linea elettrica verso più dispositivi utilizzando ben 8 terminali. Il contatto avviene in tutta sicurezza in quanto la manopola passa attraverso la posizione OFF che interrompe il passaggio di corrente elettrica. L’articolo arriva con la sua scatola di derivazione assieme a due guaine e alcune staffette metalliche. La protezione IP65 garantisce una certa protezione dalla polvere e dagli schizzi d’acqua, ma sconsiglio vivamente di posizionarlo sotto la pioggia diretta in quanto non è a tenuta stagna. La tensione nominale supportata è di 660 Volt a 20 Ampere, per cui possiamo tranquillamente gestire carichi industriali quali ad esempio motori per cisterne, martelli pneumatici, saldatrici e apparecchiature per uso professionale. Nel suo complesso, il deviatore fa il suo dovere e sembra mantenere stabile la posizione della manopola anche con l’uso intensivo. Le viti dei terminali sono di acciaio inossidabile e garantiscono una forte presa sui cavi evitando allentamenti e rischi di corto circuito. La possibilità di sfruttare fino a 8 terminali, consente di collegare più apparecchiature selezionando con un solo movimento quelle che devono accendersi o spegnersi. Oltre che in corrente alternata, il deviatore può lavorare in corrente continua permettendo di gestire dispositivi elettronici per uso domestico. Per la versatilità e l’ottimo rapporto qualità/prezzo, il mio giudizio sul prodotto è ampiamente positivo. Da consigliare.

## Questions & Answers

**Q: I plan to connect the generator output and the power company mains using this manual ts. where do i connect the 'earth' wire?**
A: The grounds are common, so the grounds can be connected together. The neutral needs to be switched through the switch.

**Q: can this take 16 mm cable in the terminals ?**
A: 16mm or 16 gauge?  It can take up to 14 gauge MAX.  I tried 12 gauge stranded and it wouldn't fit

**Q: How would i wire this to act as a spdt switch on 12v dc? i wish to switch between two power sources. any advice is appreciated.**
A: You would have to connect a jumper on the output side. (eg. sw to pos 1 will connect pole 1 and 3.  sw to pos 2 will connect pole 2 and 4. pwr source 1 to pole 1 and pwr source 2 to pole 2. add jumper btwn pole 3 and 4 and use pole 4 as an output.)  NOTE!! Check pole switching this is just an example!!!  also be aware of the amperage this is an AC switch box.

**Q: I need to switch between two ac sources, do i use 1/3/5/7 as the output? i follow that 2/6 for pos1 and 4/8 for pos2 , but what output terminals?**
A: Connect the load's hot wire to positions 1&3.
Connect the load's neutral wire to positions 5&7.
Connect AC Source #1's hot wire to 2.
Connect AC Source #1's neutral wire to 6.
Connect AC Source #2's hot wire to 4.
Connect AC Source #2's neutral wire to 8.
