Chanzon SPDT Mini Micro Slide Switch SS12D00G 1p2t 2 Position 20pcs 3mm Toggle Vertical Panel Mount Small High Knob Vertical for PCB Arduino Breadboard Electronic Board Dip Miniature SlideSwitch

It's a small switch, but it's made well. For what I need it works perfectly, and at a good price too!

I was looking for a very inexpensive switch to build up a bunch of circuit boards for my daughter's class. But even though I need cheap, I also needed functional. I did not want to have to rework a bunch of boards to replace bad switches. And out of the dozen that I've tested so far they all work perfected. They are just switching on an LED, so if there are minor fluctuations in resistance, I wouldn't notice. The only negative to point out is that they are bulk packed in a little plastic box, so do expect some bent pins. But it just takes a second to bend them back, and I haven't notice any problems caused by bending the pins back.

Tenth inch pin spacing, THANK YOU! Plugs right into the board. Very compact. Actuation is definite (not ambiguous like some slide switches), the actuator itself is long enough to actuate easily (unlike many slide switches). Looks and feels like quality low cost product. .....The fact it's SPDT makes it versatile, do stuff you can't do with SPST "on-off" switches. The pins are long enough to edge mount on some perfboards, for example my favorite Treedix 4 pcs gold plated https://www.amazon.com/dp/B0896YPD8F . And bendable enough that you can bend 'em 90 degrees and install the switch flat even in the middle of a board. These switches solve so many perfboard prototyping challenges, I'm surprised that they aren't an industry standard item. Seventy pieces... for only $6...... the little plastic box will keep me in perfboard switches for long, long time.

Works really well, however, I thought they weren't working till I figured out that I just needed to add a pull down resistor to it. I kinda wish the legs were a bit thicker, it rocks around a lot on a bread board, but I am sure the build quality works well in a perfboard. Size is small, and seems durable. Value for money spent, I can't complaint about getting 70 switches for the price.

Fits my perfboard well. Great quality. Highly recommend for SPDT switches.

I looked at a bunch of small switches for use on a breadboard for Arduino projects. All of them had some negative reviews saying that the contacts were too big to fit into the holes on a breadboard. I took a chance with these because they were cheap. For some reason, 70 of them were the same price as 20 of them so I ordered 70 of them. The contacts fit into the holes on a breadboard perfectly, they are SPDT, and the few I have tested worked fine. Great deal.

These are the correct size that several 3D printed projects I've seen and are a good size to design for in your own projects.

I wanted a discreet on/off switch that wouldn't be thrown accidentally in handling. This fit the bill. The switch -- I mean the part that gets moved -- is long enough so that it just protrudes from a 3mm panel. In the photo, you can see a USB-C port for size comparison. The switching action is solidly clicky and I'm happy that it won't be flipped unintentionally. M2.5 machine screws for mounting.
