If you are wanting to control 1 light with 3 switches this is how its done in the Uk(maybe other countries too).
A double pole 6 terminal switch could be used for all 3 switches, 2 of them having 3 unused terminals, however the indicators in the switch would not mimic the lamp being controlled, you would need a double pole switch with seperate Led indicator connections for that, I've only seen such switches as industrial selector switches which are expensive.
Or you could hack those rocker switches & bring out the leads for the Led separately.
