Lie Ryan asked How do I design a board that would switch the direction of the current on a switch of a button?

I need to design a board that will reverse the direction of the current when there a switch is pressed, and the second switch signal would reverse it again. Please tell me the name of such a layout (if it exist), or explains how it works.

And got the following answer:

look at a Flip Flop circuit. If you need any e-mail me. All you would need is a Flip Flop circuit and a DP/SP relay. Double Pole Single Throw relay. A circuit like this will say change the direction of a DC fan with a push of a button.


The relay board function exceptionally nicely with unique applications which are precise to energy distribution and protection. The relays include wide adjustment ranges having a scale that is easy to read either in 3 or 4 digits in accordance with the model. These relay board aid in rising the flexibility in the applications, cut down the overall power and maintenance charges. You will discover relays which are applied for general purposes which are available in dependable designs with swift replacement choices. And you can find models which are utilised for industrial applications and heavier duty applications that work on large loads. These goods are made to meet the lifetime industrial handle desires of the applications.
Their most current items would be the Time counter, Timer Delay, relay board, Rapid Connect Couplings, Electronic Motor Couplings, Aluminum Couplings, Morse Couplings and numerous other people. The web page gives a detailed description of every model in many categories of relay board couplings and sensors. These items are incredibly useful for high-risk applications. The relay board are also accessible with options like various timing ranges and functions. The business is at the moment seeking agents and dealers who can market and sell their factory produced products. They are always on a lookout for building new and more dependable products determined by the requires and specifications of your business.
