About this band switch, I just contact with some parts manufacturer, a bad
news, the cos t of dies markup 40% than 2 years ago I order that model 86's
! All over world deflation, but besides here!
I'm not sure exact delivery date, But I think should be before end of Feb
2011.
The new band switch is smaller than model 86 but with ALL model 86's
Specifications( even higher current rating, I add a "contact unguis") beside
size. Its size similar Model 80( not exact), So we can use it from AL-811 to
DX-4.
And all brass and beryllium copper parts are replaceable( fix using
bolt/nut, not rivet), that means when the flash over is happen, you neen't
replace whole switch!
That only still in the blue schematic, but I can send some band switch's
pictures what existing based on model 86.
