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: Be super careful until it is installed that you do not spread the layers of the switch or else... - I love this switch, the parts and makeup are robust and hearty. the contactors design to take a load. BUT.... I took off the handle and faceplates to install it onto my project door and the handle key started sliding and one of the retainer washers slid out from center. i slid the the key back a little to adjust it and just like that, "snakes in a can" 15 or so springs, contactors and metal bits erupted across the room in every direction. It was so shocking and hilarious i didnt even get mad. I wouldnt even consider trying to reassemble it as it is a crucial piece of hardware for the on/off and rotation of my lathe. I have ordered another one, but it sure would have been great information to know. just a piece of electrical tape down each side before unscrewing anything and my lathe would be running now. It is a great product and perfect for on-off-reverse, the delay just sucks. just Be Warned! ## 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.

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. ## 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.no/products/75922498-szw26-63-d303-3](https://www.desertcart.no/products/75922498-szw26-63-d303-3) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-10-06*
