2 gang 1 way light switch
You don’t see these as much now days as many manufactures only make 2 gang 2 way light switches that serve the same purpose (you just don’t use the third L2 terminal on each gang), however I thought we would include it just in case you come across one!
Basically, this is just two single way switches on one face plate

Each of the gangs (or switches) above in Fig 2 (of which there are two) work like this: when the switch is ‘on’ the COM and L1 terminals are connected together. When ‘off’ the COM is connected to nothing.
There are no connections between the two gangs in Fig 2. Each gang is a single discreet switch.

This switch arrangement is basically two two way switches on a single face plate.
Some brands of light switch may have slightly different labeling on the terminals (such as C L1 L2 or even L1 L2 and L3).

Each of the gangs (or switches) above in Fig 2 (of which there are two) work like this (Fig 3): In position 1 (when the switch is down or ‘on’), COM and L1 are connected together (just like the one way switch). In position 2 (when the switch is up or ‘off’), COM and L2 are connected together.
There are no connections between the two gangs in Fig 2. Each gang is a single discreet switch.
Just to be different:)
The terminals on your switch may be a little different to those shown above but rest assured they function just as described above but the terminal pins are in different positions. You may see the following:

The intermediate light switch is used where three or more switches control one light and used in conjunction with two two way light switches to achieve this. It is effectively two single gang intermediate switches on one face plate.

Each of the gangs (or switches) above in Fig 2 (of which there are two) work like this (Fig 3): There are four terminals, usually L1, L1 and L2, L2. In one position, L1 and L2 are connected in pairs. In the other position, alternate pairs are connected.
