Overview

Our 5v Dc Relay is a small electronic control device using DC current. With control system (also known as input loop) and controlled system (also known as output loop), it is usually used in automatic control circuit. It is equivalent to "automatic switch", which plays the role of automatic regulation, safety protection, conversion circuit and so on.

Our 5v Dc Relay adopts composite silver contacts to carry high current and increase contact stability and sensitivity. Silver alloy contacts are impact resistant, high voltage resistant, non bonding under excessive current and small contact resistance. High quality copper coil, mechanical life can reach more than 100000 times, low temperature, low power consumption, low noise and anti-interference.
