Scolmore retractive switches differences

Hi I think I’m going to get it from you experts, but here goes, I was/am fitting shelly’s to my lighting and read the Shelly dimmer thread about using the retractive switches and never asked what the difference was between the 2 way and 3 way switches and assumed they were different inside and operational from normal 2 and 3 way switches so just ordered the 3 way that someone had said they used. Now thinking about it I think I may have got it wrong and the only difference is the L1 and L2 and they all operate the same way. Can anyone clear this up before I order more switches ?
Thanks

The problem is that there is a couple of ways "2 way, 3 way" are used.

It can refer to how many physical switches are attached to the lighting circuit ie 2 way - Switch at bottom of stairs and switch on landing, 3 way - Switch at bottom of stairs, switch on landing and switch in hall

Also it can refer to the operation of the switch and that's where it gets confusing .

the retractive switches can be referred to as 2 way & centre off or 3 way, both mean top, bottom and centre

So for the cost difference just keep fitting the 3 way retractive ones even on a simple switch with just the live/switched live & neutral serving one light. So the easiest way for a non expert to call these scolmore 3 way retractive switches would be 2 way and centre off

Depends on your aesthetic and budget I wouldn’t want the extra cost or unused function on a simple toggle switch

to advise properly maybe we need to get a better understanding

Are the lighting circuits dimmable, then yes 2 way centre off. if just on/off circuits then simple toggle switch

So will be used by dimmer 2 with just one lighting circuit for this particular question, it was the scolmore pdf on their site which shows the 2 way on a lighting circuit but seems to show the 3 way with a power supply coming in

Lol so am I, I want to use a Shelly dimmer 2 on a lighting circuit which has only the live,switched live and neutral at the light switch, so one switch to one lamp, do I use a 2 or 3 way retractive switch, I’m only trying to find out what the difference in operation in the different switches ?
Thanks

looks like same switch but 3 way has the centre off button so click up or down it returns to centre, and the 2 way looks like it returns with the top after pushed in. If I’m correct or then again not don’t know lol
3 way
2 way

@RobTi Did you ever work out the answer to this one?

I'm planning to do the exact same thing as you, and use the scolmores with a Shelly Dimmer 2. I'm looking for a centre off where I can push up to turn the lights up, and push down to turn them down.

From my research I'm thinking I need the 3 way? And like you said, the 2 way is off in the top position, and is just a simple toggle switch.

Better to think and call them 3 position as 2 and 3 way mean something different when talking about light switches and can lead to confusion

As @Seb Briggs said 3 position switch centre off, I used the grid pro model and have up for top cabinet leds down for bottom cabinet leds and I can hold either up or down for both leds

Absolutely, although in the case of the linked 2 way retractive switch it is actually being used correctly, the 2 way switches do have 3 terminals, using COM and L1 is push to make and using COM and L2 will operate as a push to break switch, Scolomore do make a very slightly cheaper 1 way version of the grid switch also.

To my mind a better description for the switches you want would be 2 way, centre off but 3 position works as well.
