Abstract
Abstract The housing for an electric snap action switch has a front section with a frame having a surface serving to abut the front side of a mounting plate, and a coaxial rear section with a surface facing away from the surface of the frame and serving to abut or to be placed adjacent one side of a circuit board. A nut mates with an externally threaded tubular portion of the front section to maintain the surface of the frame in abutment with the mounting plate. The two sections are separably coupled to each other by resilient male detent elements which are provided on the front section and extend into complementary female detent elements of the rear section. The housing acts as a distancing element between the mounting plate and the circuit board, and its rear section has a recess for a switching unit which is secured to the circuit board and can be actuated by movable parts which are installed in the front section. The rear section is secured to the circuit board by screws.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
132 words
An electric switch housing comprising a front section and a rear section, said front section having a first surface facing toward said rear section and arranged to be placed adjacent one side of a switch mounting plate, said rear section having a second surface facing away from said first surface and arranged to be positioned adjacent a circuit board, means for separably coupling said front and rear sections to each other, said coupling means comprising a plurality of projections provided on said front section and extending into said rear section, said projections having portions extending beyond said second surface and having coplanar end faces disposed at the same distance from said first surface, and means for holding said first surface at a predetermined distance from the one side of the mounting plate.
Claim 2
Dependent Claim
132 words
An electric switch housing comprising a front section and a rear section, said front section having a first surface facing toward said rear section and arranged to be placed adjacent one side of a switch mounting plate, said rear section having a second surface facing away from said first surface and arranged to be positioned adjacent a circuit board, means for separably coupling said front and rear sections to each other, said coupling means comprising a plurality of projections provided on said front section and extending into said rear section, said projections having portions extending beyond said second surface and having coplanar end faces disposed at the same distance from said first surface, and means for holding said first surface at a predetermined distance from the one side of the mounting plate.
Claim 3
Dependent Claim
15 words
The housing of claim 1, wherein said second surface is parallel to said first surface.
Claim 4
Dependent Claim
16 words
The housing of claim 1, wherein said coupling means comprises a form-locking connection between said sections.
Claim 5
Dependent Claim
16 words
The housing of claim 1, wherein said rear section has a recess for a switching unit.
Claim 6
Dependent Claim
17 words
The housing of claim 4, wherein said recess extends from said second surface toward said front section.
Claim 7
Dependent Claim
21 words
The housing of claim 4, wherein said rear section includes a flange which surrounds at least a portion of said recess.
Claim 8
Dependent Claim
153 words
An electric switch housing comprising a front section and a rear section, said front section having a first surface facing toward said rear section and arranged to be placed adjacent one side of a switch mounting plate, said rear section having a second surface facing away from said first surface and arranged to be positioned adjacent a circuit board, means for separably coupling said front and rear sections to each other, said coupling means comprising at least one projection provided on said front section and extending into said rear section, said at least one projection having a portion extending beyond said second surface, said at least one projection including a resilient male detent element provided on said front section and said rear section having a complementary female detent element for said male detent element, and means for holding said first surface at a predetermined distance from the one side of said mounting plate.
Claim 9
Dependent Claim
153 words
An electric switch housing comprising a front section and a rear section, said front section having a first surface facing toward said rear section and arranged to be placed adjacent one side of a switch mounting plate, said rear section having a second surface facing away from said first surface and arranged to be positioned adjacent a circuit board, means for separably coupling said front and rear sections to each other, said coupling means comprising at least one projection provided on said front section and extending into said rear section, said at least one projection having a portion extending beyond said second surface, said at least one projection including a resilient male detent element provided on said front section and said rear section having a complementary female detent element for said male detent element, and means for holding said first surface at a predetermined distance from the one side of said mounting plate.
Claim 10
Dependent Claim
188 words
An electric switch housing comprising a front section and a rear section, said front section having a first surface facing toward said rear section and arranged to be placed adjacent one side of a switch mounting plate, said front section including a frame and said first surface being provided on said frame, said front section further including a tubular portion extending from said first surface toward said rear section and said rear section having a second surface facing away from said first surface and arranged to be positioned adjacent a circuit board, means for separably coupling said front and rear sections to each other, said coupling means comprising at least one projection provided on said front section and extending into said rear section, said at least one projection having a portion extending beyond said second surface, and means for holding said first surface at a predetermined distance from the one side of the mounting plate, said holding means including an external thread on said tubular portion and a nut having an internal thread arranged to mate with said external thread at the other side of the mounting plate.
