Experimenting with an HF oscillator, I needed to control the varactor diode voltage in precise increments over a 2V-10V range. A buffered potentiometer was the obvious choice, and connecting two pots ...

Electrical contacts in mechanical pushbutton switches often make and break contact several times when the button is first pushed. A debouncing circuit can remove the resulting ripple signal to provide ...

Rotary quadrature encoders often are used to command digital potentiometers or digital controllers, and quadrature decoding is typically performed in a programmable device (like an FPGA or ...

pushbutton encoder or rotary switch from Duraswitch, Mesa, Ariz. (www.duraswitch.com), called the thiNcoder-PB can be placed directly into layers of a membrane switch or flex circuit. A pushbutton ...

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 ...

Encoders are a vital component in many applications that require motion control and feedback information. Whether a system’s requirement is speed, direction, or distance, an encoder produces control ...
