Review: Ampper Brand Battery Disconnect Switch 12V - 48V - Well Made - This is my 3rd Ampper Brand Battery Disconnect Switch. Bottom line, I like it. I installed this one on a new battery and box install on a used travel trailer that had a battery stolen. SEE PICS... Nice quality and simple to wire and install. The lugs are good and solid and they have worked well. A 2 inch hole saw is perfect to do a surface flush mount in a battery box. I have used one in a large portable hitch mount solar power box as a disconnect. Handy for our HAM Radio power applications as well as an off grid cabin. ## Features - Heavy Duty: ABS plastic housing, durable made for safety use, rear cover insulates terminals against any short of circuits, equiped with 4 sets of bolts. - Specification: On/Off 2 positions, 275 A continuous at DC 12V, 455 A intermittent at DC 12V, 1250 A momentary at DC 12V. - Compatible: used for DC 12 - 48 V systems to isolate and secure the electrical system, can stand alone or be locked together with other switch. - Purpose: eliminate any power draw from the battery when vehicle or boat is not in use, disconnects the battery safely. - Copper terminal stud size: 3/8" (10 mm) x 2, very easy to install, universal used for car, vehicle, Rv and boat, also electrical equipment's switch. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07413JWLD | | Actuator Type | Rotary | | Best Sellers Rank | #11,692 in Automotive ( See Top 100 in Automotive ) #25 in Automotive Replacement Battery Switches | | Brand | Ampper | | Brand Name | Ampper | | Circuit Type | 2-way | | Color | On-Off | | Compatible Devices | Car, Vehicle, RV, Boat Electrical Systems | | Compatible with Vehicle Type | Universal Fit (voltage at: DC 12 - 48V systems): Marine Boat, Ship, Yacht, RV, Truck | | Connectivity Protocol | Wi-Fi | | Connector Type | Screw | | Contact Material | Copper | | Contact Type | Momentary | | Control Method | Touch | | Control Type | On/Off | | Controller Type | Push Button | | Current Rating | 275 A | | Customer Reviews | 4.7 out of 5 stars 8,701 Reviews | | Global Trade Identification Number | 00608613215417 | | International Protection Rating | IP65 | | Item Dimensions | 2.76 x 3.74 x 2.95 inches | | Item Weight | 9.34 ounces | | Manufacturer | Ampper | | Material Type | Acrylonitrile Butadiene Styrene | | Model | Am-CBS01 | | Mounting Type | Surface Mount | | Number of Items | 1 | | Number of Positions | 2 | | Operating Voltage | 12 volts | | Operation Mode | ON-OFF | | Part Number | Am-CBS01 | | Switch Type | Rotary | | Terminal | Screw | | UPC | 608613215417 | | Unit Count | 1 Count | ## Product Details - **Brand:** Ampper - **Connector Type:** Screw - **Contact Type:** Momentary - **Current Rating:** 275 A - **Item dimensions L x W x H:** 2.76 x 3.74 x 2.95 inches - **Material:** Acrylonitrile Butadiene Styrene - **Operating Voltage:** 12 volts - **Operation Mode:** ON-OFF - **Switch Type:** Rotary - **Terminal:** Screw ## Images ![Ampper Battery Disconnect Switch 12V - 48V, Marine Battery Switch Disconnect Power Cut Shut Off for Car, Vehicle, RV and Boat (On/Off) - Image 1](https://m.media-amazon.com/images/I/718K1yiT9KL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: Is there a bottom or back?** A: Yes the switch is fully enclosed except for the side you enter with the wire **Q: These are listed as being rated for 275A continuous, but the manual this switch comes with says its only 200A continuous. Which is the correct rating?** A: Thank you for your purchase. The item you recieved is On-Off battery switch, and the pamphlet you recieved is 1-2-Both-Off battery switch, so sorry for the issue casued to you, the pamphlet may be mixed by our worker. Fot the item you purchased X001H8MQTX (On-Off battery switch), the continuous rating is : 275Amps DC. Also below are some tips for you to install the switch: The 2 terminals are same, no negative and positive. Just like a switch, connected to the switch on both sides so when you flip the switch it cuts the circuit. More, recommend to install this cut off switches on the negative, not the positive (lower current in negative, will be more safety). The switch can be install in the negative wire, another short battery cable or cut existing cable and attach terminals on each end. Hope the info can help you. **Q: How far from battery can it be installed?** A: Mine is 2 feet from the battery, I don't think it matters. Your cable size will have to increase the further away from the battery that you install it. **Q: If the switch is on off (red) is the battery not drawing or the disconnect is not engaged and battery still drawing? Over thinking I'm sure.** A: battery 1 to switch,battery 2 to load side if you are using battery 2 too power stuff. if switch is off then battery 2 will power your things and not draw from main battery 1. To charge battery 2 turn switch to on then turn off when its fully charged if that makes sense ## Customer Reviews ### ⭐⭐⭐⭐⭐ Reliable and Easy-to-Use Battery Switch *by D***D on July 14, 2024* This switch has proven to be an excellent addition to my DIY projects for my custom power bank.
