Are these switches the same as the ones in the 1996? Mine works perfectly now, but if the switches are a ticking time bomb, I'm going to move it to a area with better temperature control, and start looking for a donor unit just in case. -Dave -------------- Original message -------------- From: <nnovotney@cinci.rr.com> > Had the same trouble!!! bought a junk racal unit (they have several models) for > $10 & stole the switches from it!!!

However, not all batches of these seem to have suffered the problem. If any on a unit go they may well all die. Also it is possible that they may have been replaced at some time in the past, I knew a technician at the service dept here in California who did a lot of them way back, when they were still supported... It is hard to be more specific... From examination of the dead ones I remember it was a rubber insert that died. They start to feel a bit less springy than usual, then die. My 29 cent Jameco switches have worked for me for at least five years now. I don't think you would want to have paid racal's prices for them anyway :^) dr

I desoldered one of them and it appears to be marked TOKO 30. I didn't know TOKO made switches, and none are listed on their web page. Would Racal still have them? Matt

Matt, as you are saying this I remember that i got my first set of replacement pushbuttons from a German TOKO distributor! If I memember right the name was "TOKO 3D" and not "TOKO 30" As you I found out that they don't manufacture switches anymore. All my efforts to find a supplier have not been successful.
