[Amps] Repairing early Alpha Amp pushbutton switches

[K5jv]

Greetings to all,

       I notice that Walmart is "out of stock" of the push-button switches I used to obtain the springs and contacts  used to repair my Alpha 78 multi-meter switches.  I guess the the early birds did get the wo--switches.  They do still have a similar switch.  It is blue in color and does not have the circuit board contacts.  I do not know if the internal springs and contacts are the same, or not.  I suggest using the switches from China on eBay.  They cost much less and it took only two days longer to get them, than from Walmart.

       From questions I am receiving, there seams to be some confusion about the actual repair job.  The only parts from the new switches used in the repair are the internal springs and the new, silver colored internal contacts (actually the old springs can be re-used, if necessary) You can toss the rest, or save for some other project.  You must use the original switch body (not necessary to remove it from the rail).  You must use the original push-rod.  You should re-use the original, brass colored, external spring to keep the cam-slider tension the same.  Do not remove the switches from the rail.  The four wires to the meters are all that need to be carefully removed.
