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.
Why fit a relay?
Fitting a relay is essential for controlling high-power devices with low-power signals, allowing for safer and more efficient operation. Relays help isolate sensitive components from high voltage or current, protecting them from damage. Additionally, they enable automation and remote control of electrical circuits, enhancing functionality in various applications. Overall, relays improve reliability and safety in electrical systems.

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.
Does the transmission on a 2001 Mazda Tribute have sensors or relays?
Yes, the transmission on a 2001 Mazda Tribute includes sensors and relays. Key sensors, such as the vehicle speed sensor and transmission fluid temperature sensor, provide crucial data for the transmission control module to optimize shifting and performance. Additionally, relays may be involved in controlling electrical components related to the transmission system. Overall, these components work together to ensure efficient operation of the transmission.
