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 ...

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 ...

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 ...

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 ...
