Package Includes: A 7 PIN switch, jumper wires set, and a wiring diagram. 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 contacts 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. Momentary Switch: Heavy-duty DPDT reverse polarity switch that resets automatically (returns to off) when released. Controls the up/down, clockwise/counterclockwise motion of DC loads such as motors, hoists, cranes, and linear actuators. Sturdy and Durable: Made of high-quality plastic and well-conductive pins; ensures long-lasting durability and is highly optimized for general use. Wide Range of Application: Universal fit for cars, RVs, SUVs, ATVs, UTVs, buses, marine boats, yachts, trailers, s, campers, caravans, and more. Mainly used to control winches, pumps, horns, reclining media room seats, bilge pumps, LED light bars, work lights, fog lamps, headlights, taillights, and auxiliary lamps.
