Which type of switch is known for isolating both live and neutral connections?

• A. Push switch
• B. Two-way switch
• C. Dual on/off switch
• D. Relay switch

Answer: (C)

The dual on/off switch is designed specifically to cut off both live and neutral connections simultaneously. This is crucial for ensuring complete isolation of a circuit, which enhances safety during maintenance or repairs. By disconnecting both connections, it prevents any potential electrical hazards that could arise from having one connection still energized while the other is not. In contrast, other switch types serve different functions. For example, a push switch typically only controls one line, mainly the live, without isolating the neutral. A two-way switch allows for control of a single light from two different locations but does not provide a full isolation feature for both connections. Relay switches, while they can also control circuits, primarily facilitate control of higher voltage or current loads and do not inherently isolate both live and neutral lines unless specifically designed to do so. Therefore, the dual on/off switch stands out as the correct solution for fully isolating both connections.
