Re: [time-nuts] Racal-Dana tactile switches
I know its a hack but I used a small pcb switch and use a sawn off knitting needle when I wish to press one of those buttons. It's a design fault and eventually all of them will fail.

The other day I talked to the chief technician at Rosenkranz-Elektronik which is one of the biggest surplus suppliers in Germany. He knew the problem very well and his claim was that an exact replacement for the original Toko switches is no more produced anywhere in the world. Which may be an explanation why none of us managed to find an exact repelacement. His second claim was that the switches can be repared: After removing the cap gently grip the moving part with a pair of pliers and twist it a little bit while pulling it out a bit at the same time. In this way the moving part can be removed without destruction of the switch. Then you find the source of the problem inside: The weak and mostly destroyed rubber part inside. Replace it with the rubber part of a switch which has NEARLY the same dimensions. He told me that he had done such a repair for a number of times. Unfortunately he had no reference for the switches that he had used as the source for the replacement rubber. I am aware that this is only half of the solution of the problem but I checked his suggestion with a original switch that I had laying around as a replacement and found that his description worked for me. I made a photgraph of the switch to be found here: http://www.ulrich-bangert.de/Racal.JPG and perhaps anyone of you has an idea where to get a similar one from. The problem to find a similar switch is perhaps easier to solve than to locate a direct replacement. Note that the scale in the photo is in cm with subdivisions in mm.

Re: [time-nuts] Any spare switches for Racal-Dana 1992?

Best regards, Charles That is my experience. I never managed to find any exact replacements here in England so I ended up replacing the mechanism with some SMT switches and using a probe to press them..
