AVR-Chat

Hi Folks,

I apologize up front for this OT post but I am using a ATmega48V for
this project.

I need to allow the end user to input a channel selection by sliding a
switch to one of four positions.  The trouble is I can't seem to
locate a small 4 position switch at any of the usual distributors
(Digi-key, Mouser or Newark).  The one I did find is almost 2 inches
long which is much to big for this application - it's a battery
powered hand held consumer product.

So, does anybody have any recommendations?

Thanks again,

Richard Cooke

Thanks Bob.  But for space and looks I was hoping some one could point
me to a slide switch. Something that isn't too hard to operate but not
too big either. This will be used in a product we hope to sell (300 to
500 a month)so we need a supplier that can deliver that quantity.

4pst slide switch? How about a 2 deck 4 pos rotary? Like a grayhil? They probably have something at Skycraft Surplus in Winter Park FL... they are on the web, do mail order...

A search for "SP4T Slide" at findchips.com comes up with some very small SMD ones

Those small SMD switches (aka "dip switch) are really too
small for an operator interface. They are fine for a
set/forget but pretty poor as an operator interface. Also,
they have a very limited number of operation cycles.

Slide switches are not that good for this kind of
application as there is nothing to prevent the operator
from turning on several at the same time. 

What about a multi-position "rocker" switch (with a
relatively large "paddle")? There are a number of small
SP3T or DP3T ones out there. Or, how about one of these
"rock four ways" navigation switch (lower right on page) :

Check out Grayhill and Alcoswitch web sites.

I don't think the 4-way rocker switch is the best choice.  I need the
switch to stay in position and give the end user an indication of what
 "port" they have selected.  I have seen small devices with a four
position slide switch.  I just never thought it would be as tough as
it's turning out to be to track one of these guys down.

I agree that DIP switches aren't the best fit for this application.  I
have found a rotary DIP switch that might work but it is a bit pricey
(for me) at $1.86 in 500 piece quantity.  I can buy a knob with a
pointer so the user can see what is currently selected.

Thanks,

Why use a slide switch at all?  If space is an issue, why not use a 
pushbutton switch and maybe an LED indicator for the setting.  I assume 
you're using an AVR controller.  You can program delays after which the 
setting is punched into the program and left until there's a change.

The typical multi-position slide switch that you see on consumer devices 
isn't a separate switch. Instead, it's a plastic knob that moves 
contacts that slide along your circuit board.

How about a slide potentiometer and A/D? No definite detents, but at 
least it's visible.

How about an encoder?

I don't think I can make an encoder work.  If the user happens to move
the knob while the unit is powered off I don't think I can get the
controller to figure out what position it is now in.  Or do I have
that wrong?

Richard,
Check Mouser part number: 629-g1138s1110.  It's from CW industries; they probably make it in other packages as well.  In fact, I imagine everyone makes it, distributor's just can't carry everything.
