Abstract:
1. A limiter comprising: a housing including a first surface and a second surface; a first terminal; a second terminal; a fusible conductor electrically connected between said first terminal and said second terminal; an indicator member disposed proximate the first surface of said housing, said indicator member including a first end and a second end having a first opening, a second opening and a conduit therein between the first opening and the second opening thereof, said fusible conductor passing from said first terminal, through the first opening of said indicator member, through the conduit of said indicator member, through the second opening of said indicator member, and to said second terminal; a spring biasing said indicator member away from the first surface of said housing; wherein said fusible conductor, when electrically connected between said first terminal and said second terminal, holds the second end of said indicator member proximate the first surface of said housing; wherein said spring, when said fusible conductor is electrically disconnected from at least one of said first terminal and said second terminal, moves said indicator member away from the first surface of said housing and toward the second surface of said housing wherein the edge of said shoulder is a first edge; wherein said shoulder includes a second edge; wherein the second surface of said housing includes an external opening; and wherein said spring, when said fusible conductor is electrically disconnected from at least one of said first terminal and said second terminal, moves the first end of said indicator member through the external opening of the second surface of said housing until the second edge of said shoulder engages the second surface of said housing.
