[TowerTalk] Transfer switch?

[Ron W8RJL]

Why not use two Dow Key type relays each SPST. They come in several DC 
voltages and 115 VAC. They will handle the 1500 watts, have low SWR, all you 
need is power source and a SPDT toggle switch. Dow key type relays sell for 
about $30 used last I looked, kind of old school but will sure do the job. 
You would probably want to parallel up another signal relay to switch ALC 
and key line as well so relays look like a good solution. 73 Ron W8RJL
