METHOD FOR MANUFACTURING A SWITCHING APPARATUS FOR ELECTRIC SYSTEMS

Method for manufacturing a switching apparatus for electric systems, characterized in that it comprises the following steps: - providing a first housing shell of said switching apparatus, said first housing shell being of thermoplastic material and including a first coupling edge for coupling with another housing shell, said first coupling edge having a first coupling surface and first ribs protruding from said first coupling surface and extending along said first coupling edge; - providing a second housing shell of said switching apparatus, said second housing shell being of thermoplastic material and including a second coupling edge for coupling with said first housing shell, said second coupling edge having a second coupling surface and second ribs protruding from said second coupling surface and extending along said second coupling edge; - assembling said first and second housing shells and a number of operating components of said switching apparatus, thereby obtaining a preliminary assembly of said switching apparatus; - joining the first and second coupling edges of said first and second housing shells through a vibration welding process, thereby forming a junction between said first and second housing shells and obtaining a sealed outer casing for said switching apparatus.
