A 20 Amps 2 way switch is a type of electrical switch that allows you to control the flow of electrical current in two different circuits from two separate locations. This type of switch is commonly used in homes and buildings to control lighting or other electrical devices from multiple locations, such as from the entrance of a room and from inside the room.

The “20 Amps” rating refers to the maximum amount of electrical current that the switch can safely handle. This means that the switch should not be used with a circuit that requires more than 16 amps of electrical current, as doing so could cause the switch to overheat and become a fire hazard.

Some common uses for a 20 Amps 2 way switch include:

• Controlling a light: A 20 Amps 2 way switch can be used to control a light, such as an overhead light in a room, from two different locations.
• Controlling a set of lights: This type of switch can be used to control a set of lights, such as a set of recessed lights in a kitchen or other area of a home or building, from two different locations.
• Controlling an appliance: A 20 Amps 2 way switch can be used to control an electrical appliance, such as a washing machine, dishwasher, or other large appliance, from two different locations.
• Controlling a set of electrical devices: A 20 Amps 2 way switch can be used to control a set of electrical devices, such as a group of lights or a set of appliances, from two different locations.

It’s important to follow the manufacturer’s instructions and guidelines when using a 20 Amps 2 way switch, and to consult a licensed electrician if you’re not sure how to install the switch correctly.
