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.

Lewi asked Can anyone tell me how i can switch a voltage of 230 using a low voltage supply?

I am an electrician by trade but I also have some electronic background. I don't know that much about electronics though but I need a simple circuit that can help me switch 230v using a low voltage supply (I would like the supply to be run from the same place - so the low voltage run from a transformer from the 230v supply instead of a battery). Thanks.

And got the following answer:

I am not sure if you want to convert 230VAC to a lower voltage or if you want to control a 230VAC circuit with a lower voltage. 1. Convert 230VAC to a lower voltage with a transformer then you will want a bridge rectifier with a large capacitor. Next step is a voltage regulator like a LM7805 or a LM2576 at what ever voltage you want. 2. To control 230VAC use a relay that has contacts rated at 230VAC or more, the coil voltage can be 12DC or 12AC to 115VAC or 24VDC.

The relay contact voltage work particularly well with distinct applications which are precise to energy distribution and protection. The relays come with wide adjustment ranges having a scale that’s easy to read either in three or 4 digits as outlined by the model. These relay contact voltage enable in escalating the flexibility on the applications, lower the overall energy and upkeep fees. You will discover relays that are made use of for basic purposes which come in reputable designs with rapid replacement possibilities. And you’ll find models which are applied for industrial applications and heavier duty applications that operate on huge loads. These items are created to meet the lifetime industrial handle demands of the applications.
Their most current goods will be the Time counter, Timer Delay, relay contact voltage, Rapid Connect Couplings, Electronic Motor Couplings, Aluminum Couplings, Morse Couplings and different other individuals. The web site provides a detailed description of each and every model in many categories of relay contact voltage couplings and sensors. These merchandise are incredibly helpful for high-risk applications. The relay contact voltage are also accessible with functions like a number of timing ranges and functions. The organization is currently trying to find agents and dealers who can market and sell their factory created items. They’re constantly on a lookout for establishing new and much more trustworthy items depending on the requirements and requirements of your industry.
