Details
Manufactured to military specifications by Elma in Switzerland, these are a beautifully crafted very high quality miniature concentric rotary selector switch, 2 (inner and outer) individual single pole 21 way (so 21 positions) with 6 micron gold plated over copper alloy contacts.
Make before break.
They have been carefully removed from vintage military frequency selectors, they are a concentric switch, which means they are infact 2 separate 21 way single pole switches, in one stack, with an inner and an outer control on the one shaft.
The knobs are also beautiful, and will have cost more than we are asking for the switch on its own, made by Raytheon, they are a lovely quality spun anodised heavy aluminium with deep fluting detail, the outer knob is 64mm in diameter and marked 1 - 20 and then HI in red; the inner knob is 32mm in diameter and the marking for this is 21 - 40. Overall height or depth of both knobs together is 30mm.
Obvious audio applications, with military quality and the separate controls on the single shaft.
Overall dimensions of the body behind panel are approxiamatly 55mm long x 30mm wide, the 2 hole mounting bracket can be removed to make them standard 10mm single hole mount.
As said they are removed from military test equipment but have very little use, the existing connections will have to be desoldered but then you will be left with a lovely as new switch.
Priced and supplied individually, each (x1) with knob as shown.
