3 way switches have 3 terminals. A common on and off switch only has 2.
No a 3-way is a single pole double throw. A four way switch swaps travelers.
One 3-way dimmer switch, one regular 3-way switch and one 4-way switch. The 4-way is wired between the two pairs of travelers from the other two switches. The common on the dimmer is tied to either the light or to the branch hot and the common on the other 3-way is tied to whichever is left (hot or the light).
First you need to decide what you are trying to accomplish. You can wire the Timer switch in series with or parallel to the 3-way switches. If in series then the 3-way switch function would depend on the timer state. If the Timer switch was ON then the 3-way switch could turn the connected device ON or OFF from either location. If the Timer switch were OFF the device would be OFF no matter what you did with 3-way switches. To wire in this fashion put the timer between the supply and the input to the switches. If the Timer is in parallel then if the Timer is ON it doesn't matter what you do with the 3-way switch, the device will be ON as long as the Timer is ON. If the Timer is OFF then the 3-way switches will work in their normal fashion. To wire in parallel connect the supply to one side of the Timer and the device to the other.

It can be done but it requires knowledge about how a 3way is wired to convert it to a regular switch. It would involve testing live wires to determine where power starts at. You can't just replace one switch.
No, a 3-way switch cannot be used as a 2-way switch because they are designed for different functions.

YES
To create a 3-way switch schematic for your home lighting system, you will need two 3-way switches and one 4-way switch. Connect the power source to the common terminal of the first 3-way switch, then connect the travelers to the corresponding terminals on the 4-way switch. Finally, connect the travelers from the 4-way switch to the second 3-way switch. This setup will allow you to control the lighting from three different locations.
To convert a 3-way switch to a single pole switch, you need to disconnect one of the traveler wires and connect the remaining traveler wire to the common terminal. This will allow the switch to function as a single pole switch instead of a 3-way switch.
If you have the symbol for a regular switch, a 3-way switch is the same symbol with a '3' next to it like a subscript.
No, a 3-way switch cannot be used as a single pole switch because they are designed for different wiring configurations.
No, a 3-way switch cannot be used as a single pole switch because they are designed for different wiring configurations.
A 3-way switch can be used as a single pole switch by connecting the common terminal to either one of the traveler terminals. This effectively turns the 3-way switch into a simple on/off switch, allowing it to control a single light or device.
To design a 3-way switch circuit for controlling a light fixture from two different locations, you will need two 3-way switches and one 4-way switch. Connect the power source to the common terminal of the first 3-way switch, then connect the traveler wires to the other terminals of the first switch. Connect the traveler wires from the first switch to the traveler terminals of the 4-way switch. Finally, connect the traveler wires from the 4-way switch to the traveler terminals of the second 3-way switch. Connect the light fixture to the common terminal of the second 3-way switch. This setup allows you to control the light fixture from either switch location.
No, a 3-way switch cannot be used as a single pole switch because they are designed for different wiring configurations and functions.
