Abstract

The invention relates to a push-button switch (10) comprising: • - a housing (20) made of electrically insulating material, having a lower wall (21), side walls (20a, 20b, 20c, 20d) being joined to the lower wall (21) and an open side (21') opposite the lower wall (21); • - a push-button (30) which can be used to control an electrical switching of the switch (10) and having a body provided with side walls (30a, 30b, 30c, 30d) passing through said open side (21'), the push-button (10) being designed to slide relative to the housing (20) along a sliding axis (zz), between a front position and a rear position; • - at least one elastic element (40) designed to exert a pushing force on the push button (30) to return or hold the push button (30) in the rear position;• - a first stopping system comprising the contact surfaces (251, 351) of the side walls of the housing (20) and the side walls of the push button (30) respectively, which are adjacent to each other when the push button (30) is in the rear position; • characterized in that the first stopping system comprises a button alignment system comprising alignment elements (250, 350) engaging with each other from a given point during the sliding movement of the push button (30) from the front position to the rear position.

Description

the others from a given point during the sliding movement of the push button (30) from the front position to the rear position.

Claims

DEMANDS 1. Push-button switch (10) comprising: - a housing (20) made of an electrically insulating material, comprising a bottom wall (21), side walls (20a, 20b, 20c, 20d) attached to the bottom wall (21) and an open side (21') opposite the bottom wall (21), - a push button (30) which can be actuated to control an electrical switching of the switch (10) and which comprises a body provided with side walls (30a, 30b, 30c, 30d) crossing said open side (21'), the push button (10) being adapted to slide relative to the housing (20) along a sliding axis (ZZ) between a front position and a rear position, - at least one elastic element (40) adapted to exert a pushing force on the push button (30) in order to return the push button (30) to, or to hold it in, the rear position, - additional snap-fit ​​elements (25, 35) provided on the side walls of the housing (20) and on the side walls of the push-button body (30), - !'push-button switch (10) comprising a first stopping system having contact surfaces (251, 351) respectively of the side walls of the housing (20) and of the side walls of the push-button (30) which butt against each other when the push-button (30) is in the rear position, characterized by the fact that - the first stop system includes a push-button alignment system comprising alignment elements (250, 350) engaging with each other from a given point during the sliding movement of the push-button (30) from the front position to the rear position, - said snap-in elements (25, 35) carry the alignment elements (250, 350) described above.

2. Push-button switch (10) according to claim 1, characterized in that the alignment elements (250, 350) allow the push button (30) to be aligned progressively with respect to a reference plane (RP) perpendicular to the sliding axis (ZZ).

3. Push-button switch (10) according to claim 1 or 2, characterized in that the alignment elements (250, 350) comprise at least one guide (250) with variable cross-section and a corresponding slider (350) with variable cross-section adapted to be inserted into the guide (250) with variable cross-section.

4. Push-button switch (10) according to claim 3, characterized in that the guide (250) with variable transverse section is a conical guide having a decreasing transverse section in the direction towards the reference plane (RP).

5. Push-button switch (10) according to claim 4, characterized in that the slider (350) with variable cross-section has a wedge shape.

6. Pushbutton switch (10) according to one of the preceding claims, characterized in that the contact surfaces (251, 351) are surfaces located on an inclined plane (I_P) with respect to the reference plane (RP) when the pushbutton (30) is in the rear position.

7. Pushbutton switch (10) according to claim 1, characterized in that the latching elements (25, 35) are formed so as to facilitate a forced insertion of the pushbutton body (30) through the open side (21') and, when they have passed a latching position, to achieve a latching locking coupling between the pushbutton (30) and the housing (20), on the basis of which the pushbutton (30) is slidably attached to the housing (20).

8. Push-button switch (10) according to claim 1, characterized in that the snap-in elements (25, 35) carry said contact surfaces (251, 351).

9. Pushbutton switch (10) according to one of the preceding claims, characterized in that, to stop the pushbutton (20) in the forward position, the pushbutton switch (10) comprises a second stopping system having contact elements (26, 36) provided respectively on the side walls of the housing (20) and on the side walls of the body of the pushbutton (30).

10. A push-button switch (10) according to any one of the preceding claims, comprising a system of guides distributed in space and adapted to guide the sliding of the push-button (30) relative to the housing (20) along the sliding axis (ZZ), characterized in that the system of guides distributed in space comprises - the first guiding elements (22, 32) functionally interposed between the side walls of the push button (30) and the side walls of the housing (20), - the second guide elements (23, 24, 33, 34) spaces of the first guide elements (22, 32) and places, relative to the first guide elements (22, 32), at a lesser distance from the bottom wall (21).

11. A push-button switch (10) according to claim 10, characterized in that the first guiding elements comprise a first plurality of protrusions projecting from the side walls of the housing (20) towards the side walls of the push-button (30) and a second plurality of protrusions projecting from the side walls of the push-button (30) towards the side walls of the housing (20), each being adapted to make contact with a respective protrusion of the first plurality in order to slide on this when the push button (30) slides relative to the housing (20).

12. Pushbutton switch (10) according to claim 11, characterized in that the first plurality of protrusions and the second plurality of protrusions allow the side walls of the pushbutton (30) to be spaced away from the side walls of the housing (20) when the pushbutton slides relative to the housing.

13. Pushbutton switch (10) according to one of the preceding claims, characterized in that the switch (10) is a pushbutton switch having a rocker control element (70).
