I am building a control panel prop for a small movie I am working on. My plan is to use about 25 of these https://www.amazon.com/uxcell-Button-Rectangle-Illuminated-Switch/dp/B07WQTMRHF - I only wish to show interactivity—I need these to light up when pushed and nothing more.
Good news: You aren't the first one to ask a question like this.
Check out WannabeJoy's build thread.
http://forum.arcadecontrols.com/index.php/topic,151577.0/all.htmlIt's full of detailed advice on how to do what you're trying to do including schematics, product links, how to print custom inserts for the LED buttons, add an inexpensive (<$25) no-programming sound board that interacts with the buttons, and use a USB battery pack in case you don't have power on location for your shoot.
The buttons you linked to should work just fine.
The LEDs are rated for 12v, but will light well with 5v.
- If you power 25 LEDs with 12v, they will draw about 20mA each. (25 LEDs * 20 mA = 500mA = 0.5 Amps)
-- You can use a wall-wart power adapter rated for
at least 750mA
or an arcade-style switching power supply if you want 12v for LEDs and 5v for the sound board.
- If you power the LEDs with 5v, they will draw considerably less current. (less than 200mA IIRC)
-- A USB battery pack like WannabeJoy's will be fine for this. (The battery pack link in her thread is broken, but you can use
this one instead.)
For four of the six schematic configurations that you can choose for each button, you will need to buy standard microswitches with 3 tabs. (COM - common, NO - Normally Open, and NC - Normally Closed)
- They are cheap and plentiful.
If you have any questions, please feel free to ask.
