Addressable switch assembly for wellbore systems and method

A downhole system comprising:

• a controller located at the surface;
• a gun string located in a wellbore, the gun string including plural gun assemblies and a setting tool;
• a thru-line connecting the controller to the gun string;
• and
• at least an addressable switch assembly configured to actuate a gun assembly detonator and a setting tool detonator,
• wherein a gun assembly of the plural gun assemblies includes an end plate mechanism that electrically connects to a detonator block, and
• wherein the detonator block has at least one spring-loaded contact connected to the thru-line and the end plate mechanism includes a round electrical contact made as a printed circuit board, and the spring-loaded contact touches the printed circuit board.
