 95% Alumina ceramic block case for switch case

     The Ceramic Switch block Ceramic Base is typically designed with multiple slots or holes to accommodate the electrical contacts and terminals. These slots or holes are precisely machined to ensure proper alignment and secure attachment of the components.

     In addition to its electrical properties, the high purity Al2O3 Ceramics material also offers excellent mechanical strength and dimensional stability. This ensures that the switch block base can withstand the mechanical stresses and vibrations encountered during operation, without any deformation or failure.

      Additionally, alumina ceramic has excellent electrical insulation properties, making it a safe choice for switch cases. It can effectively prevent electrical leakage and provide insulation against high voltage.

      A Ceramic Insulator of high purity Alumina Ceramic Switch Block base provides a reliable and long-lasting solution for electrical switching applications, offering excellent electrical insulation, high temperature resistance, and mechanical stability.

     Furthermore, Al2O3 ceramics are chemically inert and resistant to corrosion, ensuring a long lifespan for the insulation base. They can withstand harsh environments and exposure to various chemicals without degradation.

     In Generally, a 95% alumina ceramic block case would offer superior protection, durability, and insulation for a switch case, making it an excellent choice for demanding applications.
