The pins are too short to be used with a breadboard.
I have two of these on a breadboard right now. Maybe it’s your breadboard.
they’re just barely long enough to fit in my breadboard. I have 3 different breadboards and all the switches fit the same. They do work but also fall out with the slightest bump on the board.
That is just the nature with this type of switch. They aren’t designed to be breadboard freindly, they are designed to fit on a PCB. you will see these switches in a lot of common household electronics. Take a pair of needle nose pliers and bend the leads so they are closer/farther away. this can help ‘hook’ the button in place so it wont fall out.
GUYS! I’ve discovered an excellent technique for making these types od buttons breadboard friendly. First, using pliers, remove the kinks from the legs, making them straight pieces of metal flush with the sides of the button. Next, grab the middle of a leg with the pliers and twist 90 degrees.
!!!
SF, please add this to the description. A 90 degree leg twist… who’d have thought?
Its about time someone came up with a solution for this. I’ve straightened out the legs before, but never would I have thought to twist them.
You are a genius.
That makes so much sense. My life has been changed.
I had the same results
If you’re in the Dallas area, Tanner Electronics has these exact same buttons for 15?.
Good switches – nice height, sturdy feel
Bought dozens of these for a breadboard project. Was disappointed to find that the pins are too short, and it doesn’t seat well in the breadboard – while it’d kindof work, they’d fall out regularly.
At the same time, the long push button, (COM-08986) worked really well. I’ll be buying those in the future. Tiny variation, huge difference in how it fits in the board.
Just bend the pins a little inward and they fit perfectly.
They DO NOT stay in this breadboard…

Straightening the pins DOES NOT MAKE A DIFFERENCE.
The ones sold by Parallax are the same price, are large enough to stradle the center divide, and fit perfectly in a breadboard.
I don’t use them in the divider
Fits perfectly in a breadboard.
They may fit perfectly in YOUR breadboard but that does not mean the fit in EVERY breadboard.
Stop griping about it. Just return it, find one that works, and quiet down. Usually people just do that in the first place instead of filling up th' whole frickin' comment section with pointless flaming and web arguments.
I found this to be the case also… although the pins may be spaced at .1 inches on all breadboards, this doesn’t mean that it’ll fit and stay in nicely in all. The spring contacts may be of different tension on different breadboards, and the plastic layer between the parts and the spring contacts may be of different thickness, changing the way the legs fit. I know firsthand that they work in some, but not all breadboards, because these DO NOT stay in my mini breadboards sold here at Sparkfun, but they DO stay in my Radioshack breadboard. I like these switches, they work nice on perf boards and certain breadboards.
lol? Ok then, They fit in a 0.1 inch spaced breadboard(aka the standard breadboard :) i have your breadboard from here and 2 from parallax and a small one from here too and they fit perfectly the way i use them. I don’t put them in the center.)
Well if they don’t work for you, try to get a RMA number and try to return them.
Are you and JAA some kinda spambots who have been set to say “These won’t work with a breadboard, Booohoohoo!” no matter how many fixes people give that might work? I mean, do you even TRY the fixes before saying they don’t work? ‘cause this one seems to have positive feedback:

Nice little buttons. They do fit well in the mini ( railless ) breadboards they sell here, but I can’t get em to fit in any of my Elenco or Archer (Tandy) boards.
Hi,
I also have problems getting them stay in the 830-pin Pololu breadboards (http://www.pololu.com/catalog/product/352)
They do fit fine the wrong way around (ie the flat sides of the pins parallel to the connected lines), but then they’re useless since they’re always on…
Would be ok across the divide, but the divide is too wide (4 steps)
My solution: straighten the pins (not enough on it’s own as noted by others), then rough them up by plating them with solder
HTH, Jonathan
I was wondering if anyone knew where to find the data sheet for this part. Any help is appreciated
http://octopart.com/info/Omron/B3F-1000
There’s a datasheet + all the pertinent info there.
You can get these from Mouser too, Mouser part # 653-B3F-1000
for 22 cents, no minimums
Mouser doesn’t normally stock 653-B3F-1000 any more. However you can get a similar Mouser part 642-MJTP1230 for $.07 each; it’s the same except that it has a shorter (i.e. flush) button.
That was my first mouser purchase. 10 buttons
I just hot glued them to my board. It does not take much to hold them in and they pop off with enough pressure.
I bought 3 of these switches and none of them work. They are always on and when I push the button they read 0 v.
Contact techsupport at sparkfun dot com and we can get you taken care of
I’ve got 2 different breadboards and whoever said these “fit” has obviously never tried it.
They do fit. Are you putting it across the center(the gap)?
Is this the smallest on-off switch you have by chance?
Does this push button switch have two settings, ei: pressed completes the circuit and when pressed again it’s not?
