I am planning on building a switching box, so that my hf transceiver can 
drive one of three linear amplifiers. I have some Omron 24V contactors 
MP2-24VDC. These are rated at 25A resistive 277 VAC. They have a coil 
operated shorting bar that closes across 2 contacts, so I guess they are 
contactors. Will these be OK to switch the inputs to the linears, the PTT 
line and the outputs of each amplifier to the antenna. Since each contactor 
has 2 sets of contacts separated by the coil, I figure that I wil need six 
of them in my box.

I have heard that Teflon 50 ohm coax is good to use for the internal hookup 
within the box that I am building. Is this a good idea and does anyone know 
of a good source for 50 ohm Teflon coax.
