A two way switch is UK terminology for a North American three way switch. Though the switch has two names it is still a Single Pole Double Throw switch that has three terminals. North American terminology. The circuit is the same as the three way switch system. To control from four locations just add another intermediate switch. For the system to work properly the new intermediate switch has to be adjacent to the existing intermediate switch. The connections must run - three way, intermediate, intermediate, three way.
An intermediate or 4 way light switch has 4 terminals + 1 ground terminal.
what is example of intermediate range planning
: Blocking can occur when two switch inputs attempt to access the same intermediate switch channel.
Example: The boy was competing at an intermediate level of hockey
Well if your talking about intermediate DIRECTONS it is northeast, northwest & many more!
A three way switch is a switch that is used in a lighting circuit that allows the light fixture to be turned on from three separate locations within the building. In electrical terminology this switch is also referred to as a SPST, Single Pole Single Throw switch. The switch has three individual terminals of which two are always connected. These switches are usually located at the far extremes of the circuit with an intermediate switch between them. This intermediate switch is referred to an a four way switch.

which of these is an example of a victim operated switch
Click the link and watch a video I have posted showing exactly how to wire this configuration.
No A intermediate switch can not be used to change three phase to single phase.
An intermediate switch is a switch of 4 terminals which is used to control devices from more than 2 locations. If you want to control a device (eg. lamp) from one location you use a normal switch, you could see two terminals behind it. If you want to control from two locations you use a 2-way switch (3-way in American vocabulary), you could see three terminals behind it. But if you want the device to be controlled from more locations, you need to use what is called the "Intermediate Switch". It is to be used in conjunction with other 2-way or intermediate switches. Technically speaking, an intermediate switch is similar in structure to a Double Pole Double Throw (DPDT) with the throw contacts of a pole is interconnected to that of the other pole. Consider the stairs of a G+2 storey building. You usually have three switches -one on Ground floor, second switch on the first floor and the third on the second floor, isn't it? You need to turn-on & off the light from all locations. Then, you need to use an intermediate switch in between two 2-way switches (Can also use all three intermediate if economy doesn't matter). If you require switches in 5 locations, go for two 2-way switches in the first and last points and three intermediate switches in the rest of the locations. In each intermediate switch you could see two sets of terminals. The two wires coming from one direction is connected to one set of terminals and new two wires are connected to the other two terminals and taken to the next switch in line.
