Greetings,
I am looking for equivalent of relay or optocoupler but in nanowatts range if there is any.
I looked into a MOSFET however gate switch cannot be isolated and there is Id drop when conducting. Relay is cool because there is no current drop or voltage drop when switch is on. Timing is in millisecond range.

----- 0000------- switch
0000 ---------000000
---=====----- trigger input

however trigger input has coil which has consumes lots of watts.
Optoisolator has losses in both ways (switch and trigger input).
Voltages are of 0.4V minimum to 2V maximum. Currents are in low mAmps.
