Relays are electromechanical devices, meaning they have moving parts and are susceptible to failure. Eventually either the spring or the contacts wear out. When this happens, although the relay may still make its classic “clicking” noise when the coil is energized, it no longer completes the electrical connection between its terminals. Often a relay is at fault when a technician is troubleshooting some larger electrical circuit. Knowing for certain if the relay is the culprit will save a lot of time in the repair process.
