LB-00099

The Cherry MX Clear switch is a medium stiff, tactile, non-clicky mechanical keyboard switch in the Cherry MX family. The slider is not actually clear but colourless (in effect, translucent white). The word Clear is Cherry's own designation to distinguish it from the older ...

DF-DFR0039

We designed this board to give the user a very discrete button without any sharp edges. Button closes when you push it and opens when you release (momentary push button).

SF-COM-09940

An adjustable potentiometer can open up many interesting user interfaces. Turn the pot and the resistance changes. Connect VCC to an outer pin, GND to the other, and the center pin will have a voltage that varies from 0 to VCC depending on the rotation of the pot. Hook the cen...

PL-1400

Mini 2-pin, PCB-mount pushbutton switch on a breadboard.

AF-3643

This brilliant invention is a blessing for makers designing or using boards with standard 2.1mm DC barrel jacks. Many devices opt against a proper power switch, for size or cost or other design reasons. So, you're expected to unplug when not in use. But you want something a li...

AF-3642

This brilliant invention is a blessing for makers designing or using boards with standard 2.
