Maybe... but more is better.  I have used the P&B type RKS-5DW-12 which
are 16 amps at 277 vac.  These are the exact same as used in the DX
Engineering remote ant switch. I have homebrewed many antenns relays with
these and zero problems.  I also have used the much cheaper ($3 vs $9)
Omron (I think) JS1-12v which are 10 amps at 125 vac. Again zero problems
in heavy multi op contesting over several years.
