An electrical relay uses a low voltage, low current signal to control an electromagnet. When current passes through the electromagnet, it attracts the spring loaded arm with contactors, which will touch some stationary contactors, closing a circuit on a higher voltage/high current circuit.
An example of this is when your thermostat 'tells' the air conditioner to turn on. The voltage & current from the thermostat are low, while the voltage & current necessary to run the air conditioner's compressor are high..

Where can someone go to purchase electrical relays?
You can find some electrical relays to purchase from a website called Grainger. There is a lot of information on repair services, products, resources and you can even contact them.
What does a clicking in a ford focus fuse box mean?
The clicking in the fuse box is the relays contacting. Your relays should be clicking under normal operation.

What is electrical maintenance?
Electrical maintenance is used for maintenance of electrical equipment. Electrical Preventive Maintenance is been used for replacement of Low voltage distribution products such as ACB's & MCCB's Contactors and Relays.
What is an impedance relay?
Impedance relays are used whenever over-current relays do not provide adequate protection. They function even if the short circuit current is relatively low. The speed of operation is independent of current magnitude. Impedance relays monitor the impedance between the relay location and the fault. If the impedance falls within the relay setting, the relay will operate. The basic construction for impedance relays on which the principle of operation is easily explained is the balanced beam.
Where are the fan timer relays located on a 1989 Acura Legend?
Go to your local library and look in the auto electrical books in the reference area. They are cataloged as Japaneese, Acura, 1989, legqend, A/C, coolant system, radiator, auxillary fan operation.
Where are the relays in a 1994 Caprice Classic?
They are all located under the hood in the electrical distribution box.
Why we use relay in automatic speed controller of vehicle?
Relays are used in automatic speed controllers of vehicles to enable precise control of electrical circuits without the need for heavy-duty switches. They allow low-power control signals to activate high-power components, such as motors or actuators, ensuring efficient operation and quick response to speed adjustments. Additionally, relays help isolate different parts of the system for safety and reliability, preventing potential damage from electrical surges or faults.
