Replace on-off light switches in RV - any cheaper choices

I just went out to the RV and checked what current was being switched when I turned on my LED lights. I tried several different lights and the current draw was 0.3 to 0.4 amps. I also checked the bathroom exhaust fan which is also on the same type of switch and it drew 1.5A, but it is also on a timer that is usually used instead of the switch. I couldn't try incandescent lights since they have all been replaced by LEDs.

I am not at all concerned about the switches failing at the currents involved.
