Abstract

Abstract A miniature rotary multi-position switch capable of being mounted on a printed circuit board (2). The housing (1) and the rotor (8) of the rotary switch, are each provided with a throughgoing bore (33, 16). The rotating control shaft (17) is inserted into the bore (16) of the rotor (8), so that the shaft projects on one of the sides (3, 18) of the housing (1). This permits the rotary switch to be actuated from any optional side of the printed circuit board (2). Therefore, the printed circuit board (2) can be installed with one of its two plane sides facing the actuating side of an equipment unit, and the rotary switch can be nevertheless actuated in that the control shaft (17) is fitted accordingly. The rotary switch is mounted to the printed circuit board (2) by snap locks (5) and the rotor (8) is held inside the housing (1) with the aid of detent elements (10).

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 77 words
A rotary switch for being mounted on a printed circuit board, said switch comprising: a housing defining a throughgoing aperture; a rotor with a centric shaft, said centric shaft defining a throughgoing aperture, said rotor is frictionally mounted in said housing; and a rotating control shaft being axially adjustably mounted in the centric shaft aperture, and said centric shaft aperture being sized to adjustably receive said control shaft, and said control shaft projecting through said housing aperture.
Claim 2
Dependent Claim 77 words
A rotary switch for being mounted on a printed circuit board, said switch comprising: a housing defining a throughgoing aperture; a rotor with a centric shaft, said centric shaft defining a throughgoing aperture, said rotor is frictionally mounted in said housing; and a rotating control shaft being axially adjustably mounted in the centric shaft aperture, and said centric shaft aperture being sized to adjustably receive said control shaft, and said control shaft projecting through said housing aperture.
Claim 3
Dependent Claim 55 words
A rotary switch as in claim 1 further comprising extension means for attaching said switch to said printed circuit board, said extension means comprising plate members with ends to be inserted and projecting through apertures in said printed circuit board, said ends comprising locking means, said locking means, for snapping behind said printed circuit board.
Claim 4
Dependent Claim 26 words
A rotary switch as in claim 2, wherein said housing comprises an elastic material, with said extension means forming one structural unit with said housing part.
Claim 5
Dependent Claim 39 words
A rotary switch as in claim 3, wherein said housing further comprises the shape of a box open on one side, said open side facing said printed circuit board when said switch is attached to said printed circuit board.
Claim 6
Dependent Claim 52 words
A rotary switch as in claim 4, wherein said rotor is capable of being inserted from said open side into said housing part, said housing part comprising a limit stop for restricting the insertion depth of said rotor, said housing further comprising detent members for retaining said rotor within said housing part.
Claim 7
Dependent Claim 50 words
A rotary switch as in claim 5, wherein said rotor further comprises a stepping ring comprising elevations and recesses staggered in accordance with the contact spacing of switching steps, said switch further comprising a stop spring having at least one detent boss which is capable of lockingly engaging said recesses.
Claim 8
Dependent Claim 36 words
A rotary switch as in claim 6 wherein said stop spring comprises an annular disk, said stop spring and said housing further comprising at least one protruding tongue adapted to insertingly engage at least one groove.
Claim 9
Dependent Claim 17 words
A rotary switch as in claim 7, wherein said tongue is provided for in said stop spring.
Claim 10
Dependent Claim 31 words
A rotary switch as in claim 8, wherein said stop spring comprises two diametrically arranged detent bosses, said bosses being staggered by 90° with respect to the groove and tongue joint.
Claim 11
Dependent Claim 45 words
A rotary switch as claimed in claim 9 wherein said rotor, on its side associated with said printed circuit board, comprises several deformable plugs on which a contact spring with outwardly projecting contact blades is plugged and retained in position by deformation of said plugs.
