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 built into it so you can press onto the knob to close a separate switch....

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 right pin depending on which way the slider is pushed.

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 the button is pressed they are momentarily closed. They come in a pack...

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 with a candy-colored square cap that snaps on. You get three of each...

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 how big the actuator is). This microswitch has a 3"...

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 rubber cap that fits onto this joystick to make it very comfy...

So squishy! These silicone elastomer keypads are just waiting for your fingers to press them. Go ahead, squish all you like!
