Barcode Reader

Fixing a Barcode Reader Trigger

A few years ago I bought a barcode reader for use in a school Library. It was a Cino 780BT, Bluetooth, nice base station, glorious battery. It was a really nice unit.
One slight issue: The trigger switch on them sucks.  The first one we warrantied and got a replacement, the second one developed the same fault after a year or so of use too. The first time it happened the switch had come loose from the board, so I resoldered it back on (it’s a SMD switch, so there wasn’t much holding it on).
I contacted the company, they wanted me to send it back to them to fix (and charge me for it), the switch would be $20 + labour to fit it. I figured since it was out of warranty I’d give it a shot and see if I could replace it.

I couldn’t find a decent switch to fit (I tried to repurpose a switch from a mouse, but I couldn’t get it to fit right), so I used a switch from my Mechanical Keyboard sampler kit (it has 4 different types of switches to try out to see which one you like).

So: Little bit of soldering and some hot glue later, I have a working barcode reader again!IMG_1432
