Abstract
Abstract An electric switch comprising a trip mechanism including tiltable contact elements, support means for the tiltable contact elements and operating means for the latter connected to each other to form a single unit which is insertable through the open end of a housing into the latter to cooperate with stationary contacts in the bottom wall of the housing, and the latter is provided with a cover for closing the open end. The cover is formed with an opening through which one end portion of the operating means extends in a sealed manner when the trip mechanism is inserted in the housing.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
267 words
An electric power switch comprising a housing having a bottom wall and an open end opposite said bottom wall; two series of stationary contacts mounted on said bottom wall; a trip mechanism in said housing and comprising a mobile element of insulating material, a plurality of mobile elongated contact elements respectively substantially aligned with said series of stationary contacts and being mounted on said mobile element for limited tilting movement with respect thereto about a first axis, onepiece support means of insulating material supporting said mobile element for tilting movement about a second axis substantially parallel to said first axis, and operating means for tilting said mobile element about said second axis, said oPerating means comprising toggle means connected at one end to said mobile element and abutting with the other end against said support means, a single operating lever means mounted in said support means tiltable about a tilting axis substantially parallel to said first axis, and spring means connecting said operating lever means to said toggle means for yieldably holding the latter in a predetermined position, for holding said mobile element in engagement with said support means and for holding said other end of said toggle means abutting against said support means so that the latter together with said mobile element, said contact elements and said operating means form a single unit insertable and removable through said open end of said housing into the latter; and a cover connected to said housing for closing said open end, said cover being formed with an opening through which an end portion of said operating lever means extends.

An electric power switch comprising a housing having a bottom wall and an open end opposite said bottom wall; two series of stationary contacts mounted on said bottom wall; a trip mechanism in said housing and comprising a mobile element of insulating material, a plurality of mobile elongated contact elements respectively substantially aligned with said series of stationary contacts and being mounted on said mobile element for limited tilting movement with respect thereto about a first axis, onepiece support means of insulating material supporting said mobile element for tilting movement about a second axis substantially parallel to said first axis, and operating means for tilting said mobile element about said second axis, said oPerating means comprising toggle means connected at one end to said mobile element and abutting with the other end against said support means, a single operating lever means mounted in said support means tiltable about a tilting axis substantially parallel to said first axis, and spring means connecting said operating lever means to said toggle means for yieldably holding the latter in a predetermined position, for holding said mobile element in engagement with said support means and for holding said other end of said toggle means abutting against said support means so that the latter together with said mobile element, said contact elements and said operating means form a single unit insertable and removable through said open end of said housing into the latter; and a cover connected to said housing for closing said open end, said cover being formed with an opening through which an end portion of said operating lever means extends.
Claim 3
Dependent Claim
111 words
A switch as defined in claim 1, wherein said mobile element comprises a plurality of arms, one for each mobile contact element and a shaft portion integrally with and extending transverse to said arms along said second axis and connecting said arms at one of the ends thereof, each of said arms having a bottom face provided with a cutout in which a respective one of said mobile contact element is arranged tiltable about said first axis, and including spring means between said arms and said mobile contact elements for urging one end portion of each mobile contact element adjacent said second axis towards said bottom face of the respective arm.
Claim 4
Dependent Claim
83 words
A switch as defined in claim 2, wherein said support means comprises a plurality of first separating walls respectively arranged between said arms and each formed in a bottom face thereof with a half cylindrical seat for said shaft portion, said housing being provided with a plurality of second separating walls, each formed with a cutout for receiving said first separating walls and each also provided with a half cylindrical seat respectively complementary with the half cylindrical seat in said first separating walls.
Claim 5
Dependent Claim
22 words
A switch as defined in claim 3, wherein said first and second separating walls are provided with interfitting guide grooves and ridges.
Claim 6
Dependent Claim
82 words
A switch as defined in claim 3, wherein said operating lever means comprise a stirrup member having a pair of downwardly extending arms having at the lower ends thereof outwardly extending projections, and said first separating walls being provided with guide grooves having lower closed ends providing seats for said projections, said spring means being connected at opposite ends to said stirrup member and said toggle means and holding said projections against said seats at the lower ends of said guide grooves.
Claim 7
Dependent Claim
55 words
A switch as defined in claim 5, wherein said operating lever means comprise further a curved member connected to said stirrup member beneath said opening in said cover and having a central portion projecting through said opening, and including sealing means sandwiched between said curved member and the edges of said cover defining said opening.
Claim 8
Dependent Claim
77 words
A switch as defined in claim 2, wherein said one end portion of each mobile contact element is connected by a flexible conductor to a respective one of one of said two series of stationary contact elements and the other end portion of each mobile contact element being arranged opposite to a respective one of the other of said two series of contact elements movable in and out of engagement therewith during tilting of said mobile element.
Claim 9
Dependent Claim
19 words
A switch as defined in claim 1, wherein said mobile element and said support means are formed from polycarbonate.
