One of the joys of electronics as a hobby is how easy it is to get parts. Literally millions of parts are available from thousands of suppliers and hundreds of distributors, and everyone competes with ...

Microcontroller-based products sometimes require rotary switches. As many microcontrollers have an onboard ADC, it is easy to replace the rotary switch with a low cost potentiometer, when a rotary ...

When you need to make very tiny measurements, even noise in closed relays can throw you off. [Marco] was able to observe this effect and wanted to build a switch that didn’t have this problem. He ...

Anders has introduced a family of rotary switches that have a circular colour TFT-LCD in the middle, as well as a push button function. Available with 1.3, 2.1 or 2.47inch circular displays, the knobs ...

Available in single-, double-, and four-pole models, the MR series 0.5"-diameter, process-sealed, logic-level rotary switches employ a positive-detent mechanism and self-cleaning contact mechanisms, ...

Touting variable speed operation, a new series of rotary ac switch has three major functions. It serves as a main power switch; as the switch is rotated into the on position, it enters the ...

Two-bit Gray-coded rotary switches (aka quarature encoders) are quite rightly widely available for setting values and controlling things. And I have seen small pcb-mount hexadecimal switches for ...

Available in single-, double-, and four-pole models, the MR series logic-level rotary switches are process sealed. The switches feature a positive-detent mechanism for audible feedback, as well as ...
