Idiot here looking for suggestions or links to help me find a switch for
a gadget I'm working on. Switch needs to be 4-position rotary with 90
degree throw, with OFF-ON-ON-ON representing a full 360 deg. rotation.

ON 1 turns on 1 light
ON 2 turns on 2 lights
ON 3 turns on 3 lights

So it's like the old LOW-MED-HIGH floor lamps with three bulbs. I don't
see a way to do this with a 1P4T switch, but I do with a 2P4T. I don't
think I can use diodes because it's a battery operated thing and I don't
want to waste any power.

I think there are other "form factors" of switches but I don't know what
to look for or whether there'd be one that would be more
appropriate/simpler/smaller/less expensive than using the 2P4T option.

I might need to run an amp or two through the switch, and would rather
do it directly than use a relay, but I'm open to options.

TIA.

Diodes, power MOSFETS
