Relay switches (also called an electrical relay or an electrical relay switch) use a small amount of power to control a larger source of power connected to electrical devices such as car motors, computers, and lighting installations. A basic relay switch has a control circuit with an electromagnetic coil and a load circuit with contacts and a lever. When current flows into the relay switch, it moves through the coil and a magnetic field is created, which causes the lever in the load circuit to move between contacts, either turning the device on or off. In a normally open (NO) relay switch, when power is supplied to the relay, the load circuit is closed and the power source connected to the relay is turned on. In a normally closed (NC) relay switch, when power is supplied to the relay, the load circuit is open and the power source connected to the relay is turned off. In other types of relay switches, non-moving parts such as transistors or semiconductors can be used as the control circuit to operate the switching mechanism. Relay switches can be controlled with an external switch, such as a light switch, or they can be connected to an automatically switched power source, such as a car ignition. One relay can operate multiple switches, and multiple relays can be operated with a single switch, with each relay operating independently from the other relays in the system.
Supco manufactures test instruments and replacement parts for heating, ventilation, air conditioning, and refrigeration systems. The company, founded in 1945, is headquartered in Allenwood, NJ.

Love2Laugh:Daha asked What's the difference between cross country and track?
I want to join but, im sorta confuse on what you do.
And got the following answer:
I actually just copied and pasted this off another question I answered a few days ago, (the same question) because it was A LOT to write out. lol, not that you needed to know that :).... Track-- It is a track. The round thingy. http://www.clarkcompanies.com/Site%20Rev... <-- that's a picture from google of a track, lol. Track is officially called track and field. Events include... Sprints... 100 meters (1 straightaway of a track) 200 meters (Half a lap) 400 meters (a whole lap) 4 by 100 meter relay (4 people each run 100 meters and make up a team. they carry a buton and try to get it across the finish line the fastest). 4 by 400 relay (same as above, although each person runs 400 meters.) Distance 800 meters (2 laps) 1500/1600 meters (1500 = 3 3/4 laps around a track, 1600 = 4 laps around a track. The Olympics use 1500, but most States use 1600) 3000/3200 (7 1/2 laps, or 8 laps.) Sometimes they have a 5000 meter race, but not normally for high school. Throwing Shot Put Javelin Discus Jumping Long Jump Triple Jump High Jump Pole Vault. Hurdles 110 meter hurdles 300 meter hurdles Track is in the springtime, and has a lot of members. Cross country is in the fall. It is ONLY distance runners. It is normally a 5k (5000 meter) distance or a 3k (3000 meter) for Junior Varsity. The courses range from grass to trails to sand to mud to hills to forests, etc. Cross country is a lot more fun... You become like a close knit second family. Track is only fun to break records and stuff. Hope I helped 🙂
The 4 pole relay function very properly with various applications that are precise to energy distribution and protection. The relays include wide adjustment ranges using a scale that is certainly easy to study either in 3 or 4 digits in accordance with the model. These 4 pole relay support in increasing the flexibility in the applications, reduce the general power and maintenance expenses. You can find relays which are utilized for basic purposes which come in reputable designs with fast replacement alternatives. And there are actually models that happen to be applied for industrial applications and heavier duty applications that function on substantial loads. These merchandise are produced to meet the lifetime industrial control wants with the applications.
Their latest goods will be the Time counter, Timer Delay, 4 pole relay, Quick Connect Couplings, Electronic Motor Couplings, Aluminum Couplings, Morse Couplings and different other folks.
