4 Pin Micro Relay By D.s. Auto Relays

A 4-Pin Micro Relay is a compact electromagnetic switch used to control high-current circuits using a low-current signal. It typically consists of two output terminals (87 and 30) and two control terminals (85 and 86). When voltage is applied to the control side, the relay activates, allowing current to flow between the output terminals.

These relays are widely used in automotive systems, such as:
Headlights
Horns
Fuel pumps
Air conditioning
Ignition systems

The small size of the micro relay makes it ideal for use in tight engine compartments or modern electronic modules, where space is limited but reliable switching is critical.

Key Features:
Compact design, suitable for limited-space applications
Capable of switching high current (usually 30A or more)
Long mechanical and electrical life
Easy installation with standard 4-pin layout
Heat and vibration resistant

At D.S. Auto Relays, we ensure our 4-pin micro relays are manufactured with precision, tested rigorously, and designed to deliver consistent performance in even the toughest driving conditions.
