A 6V DC power relay is an electrical switching device that operates on a 6-volt direct current (DC) voltage source. It consists of a coil and a set of contacts that can be used to control the flow of electrical current in a circuit. When an electrical signal is applied to the coil, it creates a magnetic field that activates a movable armature, which opens or closes the contacts.

A 5V DC power relay is an electrically operated switch used to control the flow of electrical current in a circuit. It consists of a coil that is energized by a 5V DC voltage source and a set of normally open and normally closed contacts. The relay operates by using the electromagnetic field generated by the coil to attract the armature and close the contacts, allowing high-power devices to be controlled with a low-power control signal. This type of relay is commonly used in automotive, HVAC, home automation, and industrial control systems.
