Claims
- 1. An electrical circuit interrupter, comprising:
- a housing base having a recess therein, said recess having a locking opening therein;
- a module useful for performing a desirable function disposed within said recess, said module having a locking protrusion which is complementary with said locking opening, said locking protrusion and said locking opening cooperating with each other to secure said module to said housing base;
- an operating mechanism disposed within said housing;
- first and second main contacts disposed within said housing in a disposition of structural cooperation with said operating mechanism to be opened and closed by said operating mechanism; and
- wherein said module has a flexible tab depending therefrom which is useful for being pulled to cause said module to be extracted from said locking opening.
- 2. An electrical circuit interrupter, comprising:
- a housing base having a recess therein, said recess having a locking opening therein;
- a module useful for performing a desirable function disposed within said recess, said module having a locking protrusion which is complementary with said locking opening, said locking protrusion and said locking opening cooperating with each other to secure said module to said housing base;
- an operating mechanism disposed within said housing;
- first and second main contacts disposed within said housing in a disposition of structural cooperation with said operating mechanism to be opened and closed by said operating mechanism;
- a secondary cover disposed on said housing base for covering said recess when said module is disposed therein; and
- wherein said module has a flexible tab depending therefrom which is useful for being pulled to cause said module to be extracted from said locking opening.
- 3. An electrical circuit interrupter, comprising:
- a housing base having a recess therein;
- a module useful for performing a desirable function disposed within said recess, said module having a flexible tab depending therefrom which is useful for being pulled to cause said module to be extracted from said recess;
- an operating mechanism disposed within said housing; and
- first and second main contacts disposed within said housing in a disposition of structural cooperation with said operating mechanism to be opened and closed by said operating mechanism.
- 4. An electrical circuit interrupter, comprising:
- a housing base having a recess therein;
- a module useful for performing a desirable function disposed within said recess, said module having a flexible tab depending therefrom which is useful for being pulled to cause said module to be extracted from said recess;
- an operating mechanism disposed within said housing;
- first and second main contacts disposed within said housing in a disposition of structural cooperation with said operating mechanism to be opened and closed by said operating mechanism; and
- a secondary cover disposed on said housing base for covering said recess when said module is disposed therein, said flexible tab allowing said secondary cover to be disposed on said housing base.
