Enough with the motor driven rotary switches. How about stepping up to
a design solution from the 1970's or 80's?
Might I suggest a pair of 4 pole relays for each rotator??
One single pole rotary switch in the shack switches power to a pair
of those relays?
A look at the latest "All Electronics" catalog http://www.allcorp.com shows:
6VDC 4PDT relay, 5A contacts, 10 for $15.00 (enough for 5 rotators)
24VDC " " " , 10 for $17.50
Add a 6VDC, 500mA wall transformer for $2.75 (2 6V relays will draw 307mA).
Add a small rotary switch in the shack: 1 pole 8 pos $1.75 (12 pos $2.00)
A cheap, small 6 conductor control cable could control 5 rotators (plus ground).
Controls for 5 rotators = $19.50 + wire + box(es)
Controls for 10 rotators= $34.75 + wire
How's that for cheap and simple?
