The purpose of relay for life is to raise money for cancer and find a cure for it.
A relay switches heavier power loadings than a regular switch.
networking purpose
If it is a light emitting diode it is there to let you know that the relay is energized. In my experience, when a DC current is removed from a coil, the polarity of the magnetic field reverses and if it weren't for the diode, the relay would "chatter". The diode polarity is oppsite of the actuating voltage.
They seem to be the same thing. Such a device is a protective relay. It uses a microprocessor to analyze power system voltages, currents or other process quantities for the purpose of detecting faults in an industrial process system.

The Purpose of a Relay is to control multiple electrical components at once.
Headlight relay.
A relay switches heavier power loadings than a regular switch.

networking purpose
Fan (heater/air conditioning) relay switch
don't relay know
The purpose of piping as used in plumbing applications is to relay fluids such as water to households.
faster release of service brake
The relay supplies power to the fuel pump. the relay clicks on when key is turned to 'on' to power the pump.
It does not have a starter relay. It has a starter solenoid mouted on the starter which serves a similar purpose.
indoor fan relay An electric relay that starts and stops an indoor fan on cooling, electric - heating, and heat pump systems
