This rotary encoder is the best of the best, it's a high-quality 24-pulse encoder, with detents and a nice feel. It is panel mountable for placement in a box, or you can plug it into a breadboard (just cut/bend the two mechanical side tabs.) We also include a nice soft-touch knob with an arrow in it, fits perfectly and looks great. This encoder also has a push-button...

These nice switches are perfect for use with breadboard and perfboard projects. They have 0.1" spacing and snap in nicely into a solderless breadboard. They're easy to switch no matter what size fingers you have, but not so easy that they'll get flipped by accident. Work great as on/off switches or selector switches, the middle pin is connected to either the left or...

Slim clicky momentary switches are standard input "buttons" on electronic projects. These are half the width of classic 6mm tactile switches so they line up better on a breadboard, just plug them into every-other row. These work best in a PCB but can be used on a solderless breadboard as shown in this tutorial. The two pins are normally open (disconnected) and when...

Little clicky switches are standard input "buttons" on electronic projects. These work best in a PCB but can be used on a solderless breadboard as shown in this tutorial. The pins are normally open (disconnected) and when the button is pressed they are momentarily closed. These buttons are bigger than the 6mm ones we carry and come in a pack of 15. Each button comes...

Micro-switches are often found in arcade buttons and joysticks but they're also really handy in any kind of mechatronics project or when you need a basic sensor. They are always 'tactile' (clicky feeling), and 'momentary' (the switch closes when pressed, then snaps open once released). They come in a few different varieties (mostly having to do with the contacts and...

This navigation switch is an intuitive way to add 5 button's worth of interfacing with a single component. Inside is 5 switches: left, right, up, down and 'select' (pressing down), all with a common ground pin. The package isn't exactly on a 0.1" grid, but we found that you can push it into a breadboard with a little bending and it snaps in nicely. We have a nice...

Your friends probably tell you that you are "good with your hands," but now you can also be good with your feet! This foot switch is made of rubbery plastic, is plenty strong to put up with any amount of stomping, and contains a snap switch. You can use the switch as either a "normally open" or "normally closed" type. Attached to the switch is a 2 meter long cable so...

This funky user interface element is reminiscent of the original clicking scroll wheel interface on the first iPods. It's a fancy mechanical kit but has an intuitiveness that is hard to argue with - everyone knows how to use this kind of rotary encoder to scroll and select. This product is just the encoder/button wheel element. The pin-out is a little odd, we really...

Here's a new addition to our rotary-potentiometer-knob family. This knob has a nice soft-touch feel with an arrow on it, and its much 'slimmer' than the skirted knob we have been using, so good for compact layouts. Note: This is just the knob. We have a breadboard-friendly rotary encoder here. Rotary encoders are useful as rotation sensors or selectors and look...

Rotary encoders are soooo much fun! Twist em this way, then twist them that way. Unlike potentiometers, they go all the way around and often have little detents for tactile feedback. But, if you've ever tried to add encoders to your project you know that they're a real challenge to use: timers, interrupts, debouncing... This Stemma QT breakout makes all that...
