I’m looking for 10k (or 20k, or 50k) rotary potentiometer that includes a single switch. I need it to be vertical, PCB/through hole mount. I want it to function as both an on/off switch for the circuit, as well as a volume control. Hopefully there is a noticeable “click” as it turns on/off, like what you would find on an older pocket radio (where you would turn the volume dial to turn it on, and then continue to turn to turn up the volume). I just can’t seem to find anything like that on Digikey. Any help would be appreciated!
I found the 3310H-126-103L-ND. Which does have a switch in it.
However it does require a minimum order of 100 of them.
Also found a PTV09A-4220F-B103-ND which has a detent switch instead. and you can get 1 at a time.
Thanks for the quick response! Just so understand, the PTV09A-4220F-B103 has a detent, but that wouldn’t control an on/off function AND volume in a circuit? It appears to only have three connectors, so I’m assuming the detent is there to turn the potentiometer on and off? I’m really new at this so sorry if my assumptions are way off. I really appreciate the help.
- Search DK site for “potentiometer.” Select “Rotary Potentiometers, Rheotstats” family from results.
- Select acceptable range of resistance values in “Resistance” column and apply.
- Select values including “rotary” in the “built in switch” column and apply.
- Select “through hole” under “mounting type”
- Limited results including that mentioned above are shown. No good options.
- Cancel last filter selection, and replace it with selections for “Top Adjust” and “User Defined” under “Adjustment Type” and apply.
- Select “PC Pins” under “Termination Style” and apply. Options remaining are quite a bit better.
- Select “in stock” and apply. Pick from these options using any remaining filters per your preferences.
The product data is not always perfectly consistent. Because the thing you’re after could be perceived as either “through hole” or “panel” mounted, it’s a toss-up as to which value may have been assigned.
General procedure is to apply one filter at a time, starting with those of greatest interest. If one suddenly goes from All The Options to none, back up and try a different approach.
Unfortunately that’s not a “switch” per-se, but rather an indication that there’s a center-position detent. There’s an ongoing tug of war between factions that would prefer attributes in separate columns, and those that consider a multiplicity of columns to be scary and/or aesthetically unpleasant.
Thanks guys! I think I’ve found something that will work, so I’ll give it a shot. Thanks again!
