sorry, no.
you need a multi meter to find out what does what.
are you sure there are only 4 wires? (not counting earth)

Dcgc said:I am trying to replace a new two way switch to operate the hall and landing lighting. The wiring is as follows:
two red wires, two black wires and two earth wires.
Can anyone advise me of what wire goes where?
Many thanks

It may be easy.....
Is this a single switch plate with two switches on it. Are there two lights that can be swithed individually by these two switches. Are there any other switches that control either of these two lights ?

Look for the simple option first.
An old lady called me to fix a two way switch. I got there found a "two way" switch. On way it was ON and the other way it was OFF
4 wires you say... no idea...
either has to be 3 wires or 5 wires.. 4 is not an option.... can't be done that way for 2 way switching...
either live in and 2 strappers with the switched live out at the other switch, or live in, switch out and 3 strappers....

It could be an intermediate. [4]
One of the four may not be used [3]
And it is possible for this to be a 2-way setup on one switch.
Cable one carries L and SL from a fitting. Connect to switch one.
Link wire from COM to COM.
Cable two carries 2 strappers from switch two to another switch.
Someone posted last week who had this setup.

Just to clarify,
Yes it is a single plate with two switches, one switch should control the downstairs light and the other switch controls the upstairs light.
There is another single switch upstairs that controls the upstairs light.
These did work with the wiring before, just can't get them to work now.

L , SWL, and 3 strappers ( com , L1 , and L2 )

As crafty has said - this setup is fairly common.

Next time I draw quicker and also use wobbly lines.........
says 2 way on one switch quite clearly in his post.. which is what i was referring to.
although after re-reading his post he means 2 way on ONE of the switches, didn't read Dcgc's post after his stating 2 switches, one of which is 2 way..
thought he meant linking the common to the other 2 way switch the other end.. which would then be 5 wires...
