Powering My AC Mains Project with a Push-Button Timer

In summary: I have never worked with wall power before, but I think I could figure it out. After some research, this seems like the easiest solution. These things seem great! I have never worked with wall power before, but I think I could figure it out.

TL;DR Summary
Thread for controlling 110v power with a button/timer
Hello! I am trying to create a special kind of switch for a project I am working on and I am pretty stumped. Basically, I need to power a 110v fan and light for around 10 seconds with the push of a button, and then have them all turn off and be ready for another button push. My brain immediately went to relays and microcontrollers like Arduino, but I've never worked with wall power with those before. I was wondering if anyone had experience with something like this or if there were a few products that I could use together to consistently get this thing to work.
Thank you for your time!

Welcome to PF. :smile:

Can you say more about your project? 10 seconds seems like a really short time to run a fan. Can you just use one of the standard off-the-shelf AC Mains switch units (controlled with WiFi or BlueTooth or powerline comm or whatever) to do this?

Try looking up a Time Delay Relay. Many are adjustable.

The fan would be to blow a fast stream like a hand dryer. I was thinking something like an air mattress blower

FAQ: Powering My AC Mains Project with a Push-Button Timer

How does a push-button timer work in an AC mains project?

A push-button timer works by allowing you to set a specific duration for which the AC mains will be powered. When you press the button, the timer starts counting down from the preset time. Once the time elapses, the timer automatically cuts off the power supply to the AC mains, ensuring controlled usage and energy efficiency.

What components are needed to integrate a push-button timer with an AC mains project?

To integrate a push-button timer with an AC mains project, you will need the following components: a push-button switch, a timer module (such as a 555 timer or a digital timer), a relay to handle the AC load, a power supply for the timer circuit, and necessary connectors and wires. Additionally, you may need a housing or enclosure to safely contain the components.

Is it safe to use a push-button timer with high voltage AC mains?

Yes, it is safe to use a push-button timer with high voltage AC mains, provided that proper safety precautions are taken. Ensure that the timer module and relay are rated for the voltage and current of your AC mains. Use insulated wires and enclosures to prevent accidental contact with live components. Additionally, it is advisable to have a qualified electrician review your setup to ensure compliance with safety standards.

Can I adjust the timing duration on a push-button timer for my AC mains project?

Yes, most push-button timers allow you to adjust the timing duration. The method of adjustment depends on the type of timer you are using. For instance, digital timers often have buttons or a rotary dial to set the desired time, while analog timers like the 555 timer can be adjusted by changing the values of resistors and capacitors in the circuit. Refer to the timer's datasheet or user manual for specific instructions on how to adjust the timing duration.

What are the benefits of using a push-button timer in an AC mains project?

Using a push-button timer in an AC mains project offers several benefits: it helps in automating the power control, improving energy efficiency by ensuring devices are not left on unnecessarily, increasing the lifespan of electrical components by preventing overuse, and providing convenience by allowing easy control of power with a simple button press. Additionally, it can enhance safety by reducing the risk of overheating and electrical fires from prolonged operation of devices.
