What is a Relay?
A relay is an electrically operated switch. It consists of a set of input terminals for single or multiple control signals and a set of operating contact terminals.

Which type of relay is best?
Latching relays use permanent magnets to hold the armature in its current position, even after the drive current is removed from the coil.
For very low-voltage applications, latching relays are preferable because the lack of coil heating minimizes thermal electromotive force (EMF) which can affect your measurements.
How long does the relay last?
The electrical life expectancy of general purpose and power relays is generally rated to be 100,000 operations minimum, while mechanical life expectancy may be one million, 10, or even 100 million operations.
