METER WITH INTEGRATED HIGH CURRENT SWITCH

Title:

METER WITH INTEGRATED HIGH CURRENT SWITCH

Document Type and Number:

WIPO Patent Application WO/2009/146393

Kind Code:

A3

Abstract:

Disclosed are apparatus and methodology for integrating directly within an electricity meter components corresponding to a high current switch. Line and load terminals forming a portion of the high current switch also correspond to line and load terminals configured for insertion into an electricity meter socket. Plural pairs of spring elements are connected at one end thereof to the meter load terminal while the opposite ends of the spring elements carry contacts configured to cooperate with matching contacts on a conductive support. The conductive support is coupled to the line terminal by a further conductive bar that is configured to support a flux-concentrating core for measurement of current flow through the high current switch. The present subject matter has to do with integrating a service disconnect switch directly into the base of a meter so as to provide a dual functionality component.
