Lyndon;
I should have paid more attention to your original post.?
To be able to switch your tuner in and out with a single switching control (manual or relay), you need a DPDT coax switch... AKA a "coaxial transfer switch"
Unfortunately, the Bird CoaXwitch 72-2 "2 Position - 2 Circuit" transfer switch sells for $2400+ new. A used one, from RF parts, will cost you $935:
If you're willing to turn 2 knobs simultaneously, the most economical way to achieve coaxial transfer-switch functionality is with two 2-position coaxial switches. Two of the Alpha-Delta Communications coax switches mentioned elsewhere in this topic would work for that solution, and would readily meet your 200-Watt power requirement on 6M.
There are many cheaper manual coax switches available online (ebay / amazon), but I'd be pretty skeptical of a new 2-pole coax switch costing $40 or less. Look for specs for frequency-range, VSWR / loss at different frequencies, and power capacity.
