Or of course you could gang up miniature toggle switches. RS probably has a three-way pushbutton speaker or antenna switch in a 2x2x3 box with connectors (RCA or F-type) on the back. DigiKey is an obvious source. Here's a cheaper one, got a dp3t slide switch at 3/$1. <http://www.allelectronics.com/make-a-store/item/SSW-54/DP3T-ON-ON-ON-SLIDE-SWITCH/1.html > If the current through the switch is less than 18 ma the so-called "dry-circuit" switch type would be preferred, although they're a good deal more expensive. At low currents the switching action does not exert the cleaning effect on the contacts that it does above 18 ma. I think you're probably ok on that but I don't know. Yours, David |
