Refined Car Relay with Waterproof Housing and Alloy Contacts for Universal Use

The Tesnaao 4 PCS Car 12V 40A 5 Pin Relay, JD1914 Waterproof Housing and Alloy Contact Relay, is a Normally Open Normally Closed Plug-in Changeover Relay with a Plastic Handle, suitable for universal use in cars. The relay's working principle is that when the 5 pin coil is energized, the mechanical part of the contact is attracted to complete the switch state, allowing the external circuit to be connected or disconnected. This makes it suitable for use in automotive lighting systems, motors, and other applications.

The relay features 5 pins: 85 (control line power input terminal), 86 (control line ground terminal), 87 (normally closed pin), 87a (normally open pin), and 30 (total power supply enter). The presence of both normally open and normally closed terminals provides better circuit control. The relay's silver alloy contacts offer stronger conductivity and a longer service life, while the all-copper coil ensures more reliable and precise suction, lower temperature rise, stronger suction, and more stable performance.

The relay's flame-retardant shell is made of waterproof and flame-resistant plastic material, providing good thickness and smoothness, as well as resistance to high temperatures. This allows the relay to withstand various environmental challenges and ensures safer use.

The package includes 4 x 5-pin relays, each equipped with plastic mounting tabs for easy installation. The simple plug-in design allows for a straightforward plug-and-play installation. If users have any questions about the use of the relay, they can contact the manufacturer directly, who will provide a solution within 24 hours on weekdays.
