For controlling light fixtures from four different locations, a combination of three-way and four-way toggle switches would be used. Three-way switches are used in conjunction with four-way switches to allow multiple locations to control a single set of lights.
You can achieve this by using a three-way switch setup. Connect the power supply to the common terminal of the first switch, the lamp to the common terminal of the third switch, and the traveler terminals of the three switches in a loop. This way, you can turn the lamp on and off independently from any of the three switches.
Three-way switching refers to a setup where two switches control the same light fixture. This allows the light to be turned on or off from two different locations, providing flexibility and convenience. It involves using special 3-way switches and a traveler wire to connect the switches together.
To control a ceiling-mounted fan from seven locations, you would need a minimum of three four-way switches. Each four-way switch allows you to control the fan from three different locations by working in conjunction with two three-way switches.
You don't. You use a pair of two-way switches ('three-way switches' in US/Canada).
A three-way light switch wiring diagram shows how to connect three switches to control one light. It involves two three-way switches and one four-way switch. The wiring allows you to turn the light on or off from any of the three switches.
A three-way lighting switch diagram shows how to wire three switches to control one light fixture. It involves two three-way switches and one four-way switch. The wiring configuration allows you to turn the light on or off from any of the three switches.

The use of a four way switch is needed when a load (such as a light) needs to be controlled from 3 locations or more. For instance when you walk down a hallway and there is a light there are probably at least two switches one at the beginning of the hallway and one at the end. These two switches will turn the light on or off from either location. These two switches will be three way switches. When the need to control a light or a load from more that two locations arises a four way switch is introduced. A light or load can be controlled an unlimited amount of locations by adding four way switches which are wired in between the two three way switches. Think of a sandwich where the three way switches are the bread and the meat and veggies are the four way switches. You can put as much meat and veggies as you want, but you always need two slices of bread on the top and bottom.
Was it installed in a three way or four way system?

You can control a single light with two switches by using a three-way switch setup. This involves connecting the light fixture to two three-way switches, allowing you to turn the light on or off from either switch.
There are several places that store three way switches for selling in PA. Some local ones are these: Kitchen Distributors of the North Hills, Sandfree, Kitchen Switch and Switch Three Way.
I think there are more than one solution but the one I understand is to provide two by two way switches linked with two strap wires. A cross over switch is also used at some third location to 'cut' the straps, linking A to B and B to A alternately dependant on switch position.The commons are connected to live or load. I always need to draw a diagram for each pathway just to make sure.Clarification:The above answer is (semi) correct. You need two three way switches at the ends of the circuit, and one (or more) four way switches in the middle. The three way switches select between A and B for power, and the four way switches flip A for B and B for A. You can use any number of four way switches, making this an N-Way circuit. The three way switches are SPDT, and the four way switches are DPDT with an internal cross-over.

In UK parlance, you need to use a pair of two-way switches and an intermediate switch.In North-American parlance, you need to use a pair of three-way switches and a four-way switch.
