A Newer Pushbutton Proposal

2003-02-25 by Tentochi

It looks like all of the SB series pushbuttons are all
not grouped together.

This looks like the best current canidate to me:

     SB4011NOHC

This is a SPST Off-(On) button.  These also come with
2 hex nuts and 1 lockwasher.  The C denotes a red
plunger (black also available).  Pluger is made of
pholic resign.  The height from the threads is only
0.248".  Pre-travel is 0.031".  Over-travel is 0.057".
 And total travel of plunger is 0.088".

There is also a polyethylene slip-on cap that goes
over the plunger.  I really like this.  And it
increases the diameter of the plunger from 0.331" to
the cap diameter of 0.394".  The part number for the
red slip-on cap is AT422-2C.  It does increase the
hight from the threads to 0.346".

The Switch Zone listed lots of distributers for this
pushbutton.  Here is some of the NKK info on this:
