Havells "Coral" is sleek designed & has soft operation, Available in white colour with glossy finish, developed with 'insulated looping' type of wiring which is a new development in modular switches. The two-pin plug is also called the Europlug. It has two round 4 mm pins. It can be inserted in either way into the socket. Hence, there is no fixed live (hot) and neutral (cold) terminals. Universal sockets are used for both round as well as flat pin plugs. These sockets do not require an external adapter for conversion. Shuttered sockets are best for safety purpose. This additional protection provides peace of mind for parents with small children, who may try inserting a foreign object into the socket.
