10 position rotary switch with momentary button?

Does anyone know where I can get a rotary switch that has 10
positions, and when you push it, it is a momentary switch?

I don't know if anything like this even exists really.

It could have 10 distinct contacts for the rotary, or it could be
bcd... either way would be fine by me.

If it exists, I'd like it to be pretty small... like 1/2" wide and
1/2" tall... give or take a bit.

Thanks for any help.
I've been looking around... and I haven't found a 10 position rotary
switch that you can also push like a button.

I'm not sure if such beast exists, the closest would be a push button,
a debounce circuit (such as NAND gates), a 4017, and transistors to
control whatever you wanted to control.

Interesting... but in my case, I really do want a rotating knob.

Anyone else?

If you need only one, build your own. I would find a BIG knob that would
fit the shaft of mthe rotary switch. I would then install a very small
pushbutton into the knob and wire it in series with your single point of
contact that rotates. This would work only if your switch had a stop at
the end so you wouldn't endlessly twist your wires.

Otherwise, drill a hole through the center of your shaft all the way
through. Affix a pushbutton to the underside and place a plunger into
the hole. Have th plunger stick out a little on the top and cover it
with a flexible membrane. So when you push on the plunger, it then
contacts your pushbutton and completes the circuit. Even use a
microswitch for the pushbutton.

Yeah, it's a little work, but as a hobbyist, I do this kind of stuff all
the time. And if it's for production, you have a prototype for a switch
house to make for you if it's economically feasible for you.

Another DIY idea is to take a pot apart and use the shaft and wiper part,
with the bushing that holds it. Etch a track pattern of copper clad board
to form ten sectors and use the wiper to select them, and a hole through
the centre to allow a push along the shaft axis to push a switch contact
closed. How well this can work depends on far too many things to post
about, you'll have to look at a few pots and pushbuttons to see if
something will adapt.

If he's going to do that, then he might as well find a car radio with
a control that is both a variable and an on/off switch. The mechanics
are thus taken care of, and that dual shaft doesn't have to be worked out.
Extract the control/switch and use that as the basis for the construction.

I still have not found what I am looking for OTS.

As you guys suggest, I am planning on building my own. I am just
working on a hobby... and I only need one part.

Making my own, for my particular application, is really as simple as
gluing the rotary switch on top of the momentary push button.
But if one did exist, it might last longer than my homemade one.

Thanks for the suggestions.

I haven't seen what you're asking for. What you can find are
rotary encoders with detents, which also have a momentary press
switch.

The difference is that a 10-position rotary switch has a common
which connects to one of ten individual contacts for the positions,
giving an absolute position indication.

A rotary encoder only provides relative position by means of
quadrature outputs, and usually does not have an end stop, so
it can be turned more than 360 degrees.

Does it have to be a pushbutton?

You might cook up something with a metal insert in the knob, and
then some circuitry connected t the metal so it's a touch activated
switch. It would depend on the application, because I suspect
you end up with false triggering, because it's so easy to brush
against the metal, while a physical pushbutton requires real pressure
to activate.

If a similar device is found with decade count in BCD output, the 4028 BCD
to decimal decoder IC can convert to 1 of 10 outputs that track the
direction of the knob. There might be a single IC that can take a
quadrature encoder output and convert to decade BCD but I didn't find one.

Does it even have to be on the knob? Why not a button beside the rotary
control?

yeah, some of those car radio controls are gems of multipurpose functions!

my last pioneer unit had three rotary controls that did 12 functions!!

it had features i didnt even use!

even a pc mouse with rotary optical sender may be of some use.
