switches

Hi,

I'm need to do some 4-point probe measurements and I need some sort of
switch matrix, or a bunch of relays. It should be electrically
controlled, ie. so I can't connect some wires to a PC and control it
that way. Can someone give me some ideas on where to start, as far as
what type of switch components I should look at. Also, of consideration
is that fact that I will be measuring very small Hall voltages as well.

Thanks,
David
 
It looks like I can either use 4 6-pole switches or 16 relays. But I
still have no idea what kind to use, or what they would be called.
