Havells Jack cat

"Havells Jack cat" seems to be a partial phrase, and without context, it's unclear what specific product or term it refers to. Havells is a well-known brand that manufactures a wide range of electrical products, including switches, sockets, lighting fixtures, and more. "Jack cat" could potentially refer to a product line or specific item within Havells' range, but without more information, it's difficult to provide a precise explanation. If you can provide more context or clarify what you're referring to, I'd be happy to help further.
