I looked into the industrial grade buttons and they are over my budget. I know I’ll need extras. These buttons are more than $7 each and they require an additional trigger (microswitch) add on with LED, which is about $12 each. Each button will be over $20 (including shipping). I’ll need about 9 and extras.
I’m looking into arcade buttons instead, they’re about $3 each including the microswitch and RFID. If they can ship it soon, for my critique.
I opted for Arcade Buttons from eBay from the US. Usually arrives in Canada 1 – 3 weeks, so I’d still make the deadline. 10 buttons in total came to about $30 (including shipping), so it’s a lot cheaper. They’re going to be blue with LEDs and microswitches.
