How do I wire up a two gang switch

[ColinHorgan]

I am after wiring my workshop up as instructed by an electrician friend of mine. But when it comes to the light switch I'm lost?
It's a unit mounted on the wall with 2 switches. One for the lights inside and one for the outside light hanging over the doorway. Everything is in place but I'm kinda lost as to wiring it all up in the back of the switch.
My electrician friend is on a family break for a few wks and I'd like to get this sorted
Any help guys I'd really be greatful.
The back of the light switch unit has 2x common, L1 L2 and a ground terminal.

Are you saying there are 2 lights and 2 switches, and each light is controlled only by 1 switch? A single pole switch is the easiest thing to wire: assuming your line (power in) has 3 wires the black goes through the switch, white (nuetral) bypasses the switch and the ground (earth) attaches to the ground screw on the switch via pigtail and continues on to the fixture.

Are there other switches that control these same lights? Can the same light be turned on or off in more than one location?

If this is a standard "toggle" type light switch does it have the words ON/OFF embossed on the toggle itself or is it just plain?

How many wires are in each Romex coming in? Black, white, ground, OR Black, white, red, ground?

It's two switches housed in one box, most commonly found I guess in your kitchen or hallway, to control two different lights from the one location. It is the only switch on the system.
The power cable coming in from the fuseboard has live, neutral and ground wires. The diagram above looks promising I will try that. Thanks

So it's one switch location but the switch itself has two separate switches,is that what your talking about. If that's the case then all whites go together and get tucked in,same as grounds. Black hot goes on one of the two black screws, then on opposite side of switch should be two brass screws,each black from the light goes to that,so you would have a black on one side and two black wires on other side and a ground wherever that is. If that's the switch you mean.

Take a pic of switch and box if you can and can def help you out

Here's what you may have if the power source comes in the switch box.

Hmmm... Ireland... 230v... I wonder how that stuff works.

OH... I didn't notice the OP is in Ireland.

Maybe he's talking about one of these?

I would think the 240 over there is done just like the 120 is done in North America, with one hot and one neutral (grounded conductor) and except for the possible difference in standard wire colors. the OP would wire up the way pattenp shows in his illustration.

However, need to hear from someone over there that can confirm this.

Yeah it's 220v 50hz over this side of the Atlantic! PattenP that pic is what I'm goin to try and sort out with tomorrow. I'll let you guys know thanks for the help, great to see people genuine and honest just trying to pass on some knowledge or professional info without being condescending, critical or sarcastic.
This is why I love the GJ. Thanks again.

A lot of the switches I have wired in international jobs have been 2 pole switches marked with L1/L2 and common designations. Some of them though were meant to switch the neutral as well, although those were 2 pole labeled L1/N.
