Help with Button Type

[danilux]

Hi, I'm new, buiding my first arcade machine, I want to add 4 hotkey function buttons for maybe pause, access retroarch menu,etc. Special thing that one uses once in a while, I want them to be square buttons (different to the ones that come with the arcade usb encoder), I have found some but I have no idea what is the right type of button that would work with the Arcade USB encoder, what characteristic do I have to look for?

For example would these work?

Any momentary (non-latching) button will work, but those two probably aren't the best choices.   

The first one is going to be hard to mount -- designed to snap into a square hole in a metal or plastic panel.
- If you can 3d print a panel for them to snap into, they might be a decent choice.

The second one is small (12x12mm plunger), hard to press, and low-quality switch contacts.
-----------
Sanwa OBSF-24KK buttons like these are much higher quality, but they are square body snap-in mounts.   

There are some illuminated pushbuttons like the 26x26mm ones here that would be a good choice.
- Even if you don't light them, they would also allow you to do custom printed inserts. (search for my posts containing "avery 18665")



Suzo-Happ makes regular and low-profile square buttons in various colors.
- Easy to mount in a wood panel.
- You can do printed inserts.
- It's usually a good idea to order from a reseller instead of direct from Suzo-Happ.
- You can probably find similar buttons on aliexpress.   

If you want to light the buttons, use LEDs instead of the incandescent bulbs that usually come with the buttons.
- 5v from the encoder PCB will light the 12v wedge-base LEDs usually used with illuminated arcade buttons.
- A bulb draws too much current (500mA@5v?), each 5v LED draws about 20mA@5v, each 12v LED draws about 5.83mA@5v.

That was such helpful kind reply PL1, those Sanwa OBSF-24KK are pertect for what I need, even tho they are snap-in mounts, actually, all my buttons are snap-in mounts, I didn't even knew there were screw ones before I bought them, rookie mistake, I just hope they ship to chile, thank you everything is more clear now
