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.

kajih asked design buck booster using an electromagnetic relay for constant voltage output from a varying voltage source?
planning to connect a electromagnetic relay in series with a varying source voltage source .The relay acts to break and complete the circuit when then the electromagnet is energized .I then connect my constant load across the the electromagnet(inductor) of the relay in series with a diode such that the diode conducts when the relay is off. can this produce a constant voltage across the load since from what i think the frequency of relay is dependent on input voltage.the higher the voltage the higher the frequency and vice versa. is it right that there will be constant energy stored in the inductor since for low voltage low frequency there is more time to store the energy in inductor and for high voltage high frequency lesser time to store energy in inductor. the energy stored energy in inductor is to be then released to load at constant voltage when relay is in off state. help with some other type electromechanical way to get constant voltage and calculations involved.THANKS.
And got the following answer:
The circuit you describe "electromagnetic relay in series with a varying source voltage source .The relay acts to break and complete the circuit when then the electromagnet is energized" is a buzzer. If you "connect my constant load across the the electromagnet(inductor) of the relay in series with a diode such that the diode conducts when the relay is off" then the energy released when the contacts break will be absorbed, and the relay wont wear out (you can get around 1 - 10 million operations normally) the frequency depends on the pull-in time and the drop out time. Pull-in time depends on the energy remaining in the coil when the contacts close, ; the resistance and inductance of the relay, and the voltage applied; and the magnetic flux (or stored energy) needed to open the contacts.. drop out time depends on the size of cap used to store the energy released when contacts open, and circuit resistance; and the magnetic flux (or stored energy) at which the contacts will no longer hold open. "is it right that there will be constant energy stored in the inductor since for low voltage low frequency there is more time to store the energy in inductor and for high voltage high frequency lesser time to store energy in inductor." roughly, yes but it WONT be exact, because of sticktion in the relay. All I can say is get a decent relay and try it. What a great experiment! do contact me if I can be more help!
