The original makers of that switch (Omron?) stopped making them years 
ago.  I wonder why? 

The last time I did this I found a switch at Jameco that was a near 
exact replacement.  The only difference was that the button was a little 
too loose a fit and needed a dab of epoxy inside to hold it firmly in 
place.  These have been working in mine now for at least five years.  
The type I used was KIE22 (29 cents each in 100s), however the ones I 
got then with  a cross section shape blue plunger do not look exactly 
the same as the ones pictured in the current on line catalog.  Some 
further research is indicated obviously...

Once they start to go they will all need to be replaced, I'm afraid.  

Good luck,

Dan
