1 gang 2 way意思

"1 gang 2 way" is a term commonly used in the electrical industry, particularly in the context of electrical switches and outlets. Here's what it means:

• 1 gang: Refers to the size of the electrical box or the space where the switch or outlet is mounted. A "1 gang" box is a standard single-space box that is designed to hold a single device or switch.

• 2 way: Indicates the type of switch or outlet. A "2 way" switch allows you to turn a light on or off from two different locations. In other words, it allows you to control a light fixture from two switches.

So, "1 gang 2 way" would describe a single-space electrical box containing a 2-way switch. This configuration is commonly used in rooms where it's convenient to have multiple points of control for lighting, such as in a hallway where you might want to turn the lights on or off from both ends.
