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.

How can an intermediate switch be used with a 2-way switch system to control a light from four floors?
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.
What effect would occur if the intermediate switch were replaced by a double-pole switch?
This looks like a question that has come out of the middle of a conversation. Us poor guys trying to answer the question don't have any context. We don't know what the intermediate switch is; or anything else about the system. You can always use just one side of a two pole switch to replace a single pole switch.
Can you use this switch for three phase incoming and single phase outgoing?
No A intermediate switch can not be used to change three phase to single phase.
Intermediate switch layout?
The strappers from each two way switch go to the four way switch. The strappers from one switch go to terminals 1 & 2, the other two go to terminals 3 & 4.
When installing lights with 2-way and intermediate switching control the intermediate switch must be connected to the?
to wire a lamp to be controlled from three places you need two three way switches and one four way switch. the two traveller wires that would normally run between the two three way switches must be connected to the terminals of the four way switch

How many terminal does an intermediate way lighting switch have?
An intermediate or 4 way light switch has 4 terminals + 1 ground terminal.
How is blocking related to a crossbar switch?
: Blocking can occur when two switch inputs attempt to access the same intermediate switch channel.
What is a 3 way switch?
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.
What is a 3-way switch?
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.

No A intermediate switch can not be used to change three phase to single phase.
How do you install an intermediate switch with 2 two-way switch?
Click the link and watch a video I have posted showing exactly how to wire this configuration.
Intermediate switch layout?
The strappers from each two way switch go to the four way switch. The strappers from one switch go to terminals 1 & 2, the other two go to terminals 3 & 4.

to wire a lamp to be controlled from three places you need two three way switches and one four way switch. the two traveller wires that would normally run between the two three way switches must be connected to the terminals of the four way switch
What effect would occur if the intermediate switch s3 were replace by a double pole switch?
You seem to be referring about a 3 way lighting circuit. If the cross over switch is replaced with a double pole switch, depending on how the switch was wired into the circuit, the load lamp would either stay on or not light at all. A circuit in a three way configuration has two traveler legs between the two switches The intermediate switch in the circuit just switches the two traveler legs from open to close depending on the position of the other two switched. Google, three way switching, they have many diagrams to work from.
