Please wire a relay if you are going to hook an accessory that is over 20AMP at a 12VDC power source. Or the switch will be burnt out due to its high current. Review: Function, fit and feel is great. LED adds more value for night boating. - This switch is the proper way to install an electric windlass on your boat. Many folks don't understand that a windlass installation (high current) should go through a windlass relay, and not the switch. Many installers try to attach the switch directly to the power of the windlass. This switch simply supplies the control to activate the relay. The LED on this up/down switch is perfect for night boating. The switch has a good feel and seems to be high quality. My windlass is installed with this switch and functions fine. Review: Works well - Good quality switch. I used to bypass a bad body control module and wire a window motor directly. Saved me hundreds doing it this way. ## Features - Momentary Switch: Heavy duty DPDT reverse polarity switch resetting automatically (returns to off) when released. Controls the up/down, clockwise/counterclockwise motion of DC loads (e.g. motors, hoists, cranes, linear actuators etc.). - Dual Operation: This momentary electrical system switch is used for jogging or inching operations. A DPDT switch is equivalent to two SPDT switches. It routes two separate circuits. Connecting each of two inputs to one of two outputs. The position of the switch determines the number of ways in which two contact can be routed. Always make sure you are using a switch and wire sufficient to handle the load you are carrying. In higher draw applications, a relay may be needed. - Wide range of application: Universal fit for all cars, RVs, SUVs, ATVs, UTVs, Cans, Buses, Marine boats, Yachts, Trailers, Jeeps, Prerunners, Campers, Caravans etc; Mainly used to control Winch, Pump, Horn, Reclining Media Room Seats, Auto Bilge Pump or led light bar, led work lights, fog lamps, headlights, taillights and auxiliary lamps, etc. - Sturdy and durable: made of high-quality plastic and well-conductive pins; ensure long lasting durability, highly optimized for general use and will give you a pleasant experience. - Package Includes: A 7 PIN switch, jumper wires set and a wiring diagram. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BJ2C8TGC | | Actuator Type | Push Button | | Best Sellers Rank | #40,173 in Automotive ( See Top 100 in Automotive ) #69 in Car Toggle Switches | | Brand | Nilight | | Brand Name | Nilight | | Circuit Type | 2-way | | Color | Momentary Down Up Switch | | Compatible Devices | Winch, Pump, Horn, Reclining Media Room Seats, Auto Bilge Pump, led work lights, headlights, taillights, etc. | | Compatible with Vehicle Type | Cars, RVs, SUVs, ATVs, UTVs, Boats, Trailers, Jeeps, Campers, Caravans | | Connectivity Protocol | X-10 | | Connector Type | Plug In | | Connector type | Plug In | | Contact Material | Metal | | Contact Type | Normally Open | | Contact type | Normally Open | | Control Method | Touch | | Control Type | Manual | | Controller Type | Wired Controller | | Current Rating | 20 Amps | | Current rating | 20 Amps | | Customer Reviews | 4.7 out of 5 stars 525 Reviews | | Global Trade Identification Number | 00840323901574 | | Included Components | 1PC Rocker Switch | | International Protection Rating | IP65 | | Item Dimensions | 25 x 25 x 25 millimeters | | Item Type Name | Rocker Switch | | Lower Temperature Rating | 1 Degrees Celsius | | Manufacturer | Nilight | | Material Type | Plastic | | Model | 90251B-A | | Mounting Type | Panel Mount | | Number of Items | 1 | | Number of Positions | 2 | | Operating Voltage | 12 Volts | | Operating voltage | 12 Volts | | Operation Mode | OFF-NONE-ON | | Operation mode | OFF-NONE-ON | | Part Number | 90251B-A | | Smart Home Compatibility | Not Smart Home Compatible | | Specification Met | CE | | Switch Type | Toggle | | Terminal | Spade | | UPC | 840323901574 | | Unit Count | 1 Count | | Upper Temperature Rating | 1 Degrees Celsius | | Wattage | 240 watts | ## Product Details - **Connector type:** Plug In - **Contact type:** Normally Closed - **Current rating:** 20 Amps - **Operating voltage:** 12 Volts - **Operation mode:** OFF-NONE-ON ## Images ![Nilight Down Up Polarity Reverse Switch DPDT 20A 7PIN Momentary Rocker Switch ON Off ON Switch 12V 24V Toggle Switch Jumper Wires for Control Motor for Hoist, Crane, Linear Actuator, 2 Years Warranty - Image 1](https://m.media-amazon.com/images/I/7169IwFEncL.jpg) ## Questions & Answers **Q: Can i use this as and overdrive button?** A: No this is a momentary switch it will only activate if held in the up or down position.
