Which of the following is NOT a characteristic of a 4-way switch?

A 4-way switch is specifically designed for use in circuits alongside two 3-way switches to allow for control of a light from multiple locations. It functions as an intermediary switch, connecting between the two 3-way switches.

The choice stating that it can act independently of 3-way switches is not correct because a 4-way switch cannot perform its function without being part of a circuit that includes 3-way switches. Its purpose is to provide additional control points in conjunction with those switches, allowing for greater flexibility in lighting control.

On the other hand, a 4-way switch indeed has three terminals, which accommodate the connections necessary for its function in the circuit. It also typically lacks ON and OFF markings, as its position does not directly determine the state of the light—it simply changes the path of the current depending on the position of the 3-way switches.
