The JWSR5118840 Auto Switch Relay is a versatile and efficient solution for various automotive applications that require the control of electrical circuits through a 12V DC input. This relay solenoid operates on a latching mechanism, allowing it to remain in the last position it was switched to until it is actuated again.
The dimensions of this relay are compact, measuring approximately 2.2 inches in length, 1.7 inches in width, and 1.2 inches in height. It is designed with a robust and durable construction, featuring a die-cast aluminum housing that can withstand the rigors of automotive use. The relay contacts are rated for a maximum current of 15 amperes, ensuring reliable and consistent switching for heavy electrical loads.
The JWSR5118840 Auto Switch Relay comes with a 12V DC coil that requires a minimum of 10V DC to activate. It can be operated in two modes: normally open (NO) and normally closed (NC). When the relay is in the NO mode, the contacts are open when the relay is de-energized, and they close when the relay is energized. In the NC mode, the contacts are closed when the relay is de-energized, and they open when the relay is energized.
This relay also features a built-in diode across the contacts, which helps to protect the coil from inductive kickback when the contacts open. The relay terminals are clearly labeled with the IN, NO, NC, and COM designations, making it easy to connect to various electrical systems.
The JWSR5118840 Auto Switch Relay is suitable for use in various automotive applications, including fuel pumps, water pumps, compressors, and electrical accessory control systems. Its compact size, robust construction, and reliable switching performance make it an ideal choice for automotive enthusiasts and professionals alike.
In summary, the JWSR5118840 Auto Switch Relay is a high-performance, compact, and durable 12V DC latching relay solenoid designed for various automotive applications. It features a die-cast aluminum housing, compact dimensions, reliable switching contacts rated for up to 15 amperes, and a built-in diode to protect against inductive kickback. Its versatile operating modes and ease of installation make it an essential tool for automotive enthusiasts and professionals seeking to control heavy electrical loads in their vehicles.
