The switches are available in the US from mouser.com.? Search on their web site for?SKQJLBA010? .? That is the exact ALPS switch that Icom ships as a replacement part.? It is a different model than the original switch was in that it is sealed and is rated for more cycles.? They currently only have 16 in stock, with 1000 on order.? Cost for quantity 1 is $1.13.? The sealed switch has a dark gray button instread of the original unsealed switch which had a red putton.
It is important when installing the switch to use minimum heat on the leads, to prevent oxidizing the contacts.??The maximum tip temperature spec is 662 degrees F (350 C) using a 20 watt iron, applying heat for a maximum of 3 seconds to each lead. ?No flux solution should be applied to the board or switch leads (just use flux core solder).? That is per ALPS specifications.
I forget if Mouser has a minimum order amount.? If so, they are a good source for Fair-Rite ferrite chokes.
