The switching configuration gives many ways to hook this up and achieve a lot of switching combinations. I was using to switch my RV from batteries and solar power, to AC shore power. It's capable of handling the high amperage and can switch all legs (pos. & neg.). A word of caution: The switch is made to mount on a thin surface (maybe 1/8" at the most). To mount it on the 7/8" thick bulkhead in my RV, I had to make a shaft extension that could attach to the switch shaft & fit into the knob. Although you can find literally dozens of these in 1/4" sizes, there are none I could find ANYWHERE in the rediculous metric 6mm. Hence, had to custom make on the lathe. Also had to find longer metric screws. Just lettin' ya know. Review: works great for a custom shutoff switch - I have my tesla nema 14-50 charger in a metal box but planned to upgrade to a dedicated tesla home charger (until they raised the price from $350 to $450!). Wanted to retain the option of using the 14-50 plug so customized the box with this switch to run both off the same circuit (but never at the same time). In the picture I have the 240v supply running to the back half of the switch with jumpers between bank (1/5/9) and bank (3/7/11). When the switch is in position 0, all contacts are disengaged in in the OFF position. When the switch is in position 1, bank (2/6/10) is energized and will eventually be connected to the breakers on the left which will run to the new Tesla home chargers. When the switch is in position 2, bank (4/8/12) is energized which is connected to the NEMA 14-50 outlet shown. The only thing I wish this came with is a cap or covers for prevent accidental contact with the exposed terminals. I have some electrical tape on it for now but will try to make something out of plastic. On the door, there is a dedicated power meter measuring how much power is being drawn at any given time. ## Features - 【3-Position 1-0-2 Operation】Features a 3-position (1-0-2) rotary mechanism, allowing selection between two circuits with a center-off position for secure isolation in three-phase applications - 【3-Section Modular Design with 12 Screw Terminals】The 3-section modular construction features 12 screw terminals, supporting organized and secure wiring during panel building and equipment manufacturing - 【63A Thermal Current Rating】Rated at 63A thermal current (Ith) and 660V insulation voltage (Ui), designed for power distribution and motor control applications requiring reliable performance - 【Durable Construction】 Built with a flame-retardant PC housing for thermal stability, galvanized copper components, and silver alloy contacts.

Hook up dryer to pin 1+ 5 main power in on 2 + 6, for pos 1-- also add jumper to 2 + 4 and a jumper to 6+8 for pos 2 then add Water heater to 3+ 7 . This should work to flip power. **Q: Anybody have a wiring diagram for this unit to connect a 240v 50a circuit? need a switch to change between feeding a 50a outlet and 50a piece of equip** A: All the instructions come in Chinese with a very vague chart. You must be greatly intuitive to figure it out with a meter. Good luck I'm still trying. **Q: It has a label that says 240v / 2.5a ith=63a. what does 2.5a mean?** A: That’s strange, mine doesn’t say that. It should be 660 volts and 63amps. I have mine between 30amp shore power a 1500 w inverter for my RV **Q: Can this be used to switch between two 50 amp outlets for charging an electric vehicles?** A: Absolutely but I wouldn't push 50 through it. I'm not sure what it's rated at but would easily do 30 A ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great for Shore/Battery power switch! *by &***; on October 30, 2020* Great switch, good price & worked perfectly for my application.

The box is perfect size, has knockouts in the right palces, has screw holes and the cover is made to match up with the rotary switch. The switch is beefy, solid terminals, good screws, nothing stripped out while I was installing. The switch turns into position with a soilid clack, seems sloid ## Frequently Bought Together - Baomain Universal Rotary Changeover Switch SZW26-63/D303.3 660V 63A 3 Position 3 Phase - Baomain Master Switch Exterior Box LW28-63/4 Work for Universal Rotary Changeover Cam Switch SZW26-63 660V 63A 3 Position 3 Phase - APIELE Changeover Selector Switch 3 Position 440V Universal Rotary Cam Selector (20A 12 Terminal) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.pa/products/75922498-baomain-rotary-changeover-switch-63a-3-position-12-terminal-cam](https://www.desertcart.com.pa/products/75922498-baomain-rotary-changeover-switch-63a-3-position-12-terminal-cam) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-08-10*
