It sounds like the DX and MFJ are out because of Watt limitations (200W?).
You are misinterpreting the ratings.
The ratings are for power from the transceiver sent out THROUGH the device,
not transmitter power to some other system not directly connected to the
device.
The switches go between the radio and amplifier. This means unless you have
a radio with more than 200 watts driving your amplifier, they are fine in
the intended application.
If you use them as a receiver line limiter or disconnect, and do not intend
to transmit through them, the power rating does not apply at all because it
is an external system. In that case, the power rating would depend on mutual
coupling between transmitting and receiving antennas and impedances of the
receiving antenna system.
A "power" rating would be impossible to define because systems vary so much,
but it would be many kilowatts even with close antennas.
