[Amps] Band switch

[peter chadwick]

Those switches are good for at least 20 amps, so parallleling contacts is unnecessary, especially as for bandswitches, you don't (or shouldn't!) hot switch.  Stacking sections to turn them into n-pole switches (which I think is probably what you want)  is more difficult; some probably 20 years or so ago, there was an article in CQ magazine about doing that. It really needs workshop facilities, but is possible. Two of them would give a 2pole 6way switch.

Has anyone tried paralleling contacts on this switch by stacking sets vertically using 0.100" spacers? Thinking about using this approach for my tank circuit band switch for my 4CX1500B push-pull amp project. 

One pole 6-POSITION CERAMIC TAP SWITCH for 100 W BC-375 / BC-191 transmitter tuning unit.
