Working Principles

The SR2PARU signal relay operates based on the principle of electromechanical switching. When the coil is energized, it generates a magnetic field that attracts the armature, causing the contacts to change position. This action either opens or closes the circuit, depending on the relay's configuration. The relay's small size and low power consumption make it ideal for use in electronic devices where space and energy efficiency are crucial.
