Sorry, this product is no longer available for purchase.
I recently purchased the Big Red Dome Push Button and love it, what a great button. However, it comes configured to use 12 Volts (12V) which means you need to figure out how to use it with your Raspberry Pi or Arduino projects.
Big Dome Push Button Voltage Hard to Use with Raspberry Pi or Arduino
While the switch itself works across multiple voltages, the LED bulb on the big dome push button is set up for 12 volts (12V). This doesn't work well when you are trying to use it in a Raspberry Pi or an Arduino project. In order to solve this problem, you can provide a secondary power source of 12 volts (12V) to power the big dome push button's LED. This is a bigger process since you then need to interface with the higher voltage to control it rather than just using the Raspberry Pi or Arduino output pins. Another option is to modify the big dome push button to have it accept either the 3.3 volts (3.3V) or 5 volts (5V) provided by the Raspberry Pi or Arduino. Modifying the big dome push button provides the easiest method of allowing you to keep your project simple.
Solution: A Big Dome Push Button Configured for 3.3 Volts (3.3V) or 5 Volts (5V)
As a handy person, you can obviously take the time to configure the big dome push button for use with 3.3 volts (3.3V) or 5 volts (5V) or anything in between. But why would you waste your time when we can build it for you! You have more important projects to build than to modify the big dome push button so we are providing our solution to you.
