What is intermediate switching?
An intermediate switch is a three way light switch. It is used when you have three or more switches controlling one light, the middle switch needs to be an intermediate light switch. This can be continued for multiple switches, so it applies to three or more switches.
How does an intermediate switch work?
Intermediate Switches are used for when there are three switches (or more) controlling one light. On this circuit you would need the middle switch (the one at the top of the stairs) to be an Intermediate Switch. This circuit can then be continued for multiple switches where there are three or more switches.
How do you wire a 2 way intermediate switch?
To use an intermediate switch as a two way switch you can use one of the top L1 terminals for the COM, then use the bottom two terminals for what would be the L1 and L2 on a normal two way switch.
What does 10ax mean on light switch?
These are plate switches, fully rated for fluorescent or inductive loads. BS 3676. ( X rated for use with fluorescent and inductive loads as well as standard). This avoids the need to derate the lighting switch.
What is the difference between single way two-way and intermediate switch?
One-way switches only have two terminals while two-way switches have three. A two-way switch can be used to control a light from two locations while a one-way switch cannot. 3. One-way switches have definite on and off states while two-way switches don’t.
What is the difference between single way two way and intermediate switch?
What is a 2 way intermediate light switch?
An Intermediate Light Switch is where 3 lighting points control the same circuit. On a staircase, a light switch at the bottom and at the top of the stairs controlling the landing light circuit would be a 2 way circuit.
What does the ax stand for on light switches?
The ‘X’ means that the rating of the switch still applies on inductive as well as resistive loads.
Can I use a 10 amp light switch?
Yes, any bulb that falls within the wattage range of the dimmers can be used. The minimum load on the dimmer module is 10W. This means there will be no dimming effect if the combined bulb wattage is 10W or less. If the combined wattage you are using is too low, it may cause your lights to flicker.
When do you use an intermediate light switch?
Intermediate switch wiring diagram (new cable colours) 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.
How is an intermediate switch connected to a terminal?
When the switch knob is up, the terminal contacts of intermediate switch connect terminal A with terminal C and terminal B with terminal D as shown in fig 1a. On the other hand when knob is down, terminal A is connected to terminal B and C to D then. Fig 1: What is Intermediate Switch & How it Works?
What do you call a 4 way switch?
Good to know: Intermediate Switch is also known as 4 way switch. In an intermediate switch, there are four terminals by which it changes the flowing of electric current from one circuit to another (see fig 1 & 2) and also known as three way switch. It has the ability to ON and OFF the electric supply by two ways.
Where is the middle switch on a circuit?
On this circuit you would need the middle switch (the one at the top of the stairs) to be an Intermediate Switch. This circuit can then be continued for multiple switches where there are three or more switches.
