Definitions
- the invention relates to a snap disk switch according to the preamble of the claim 1 with a domed snap disc, which has at least two support elements is supported on a basic element.
- Such snap disk switches are well known in the prior art and are mainly used in the area of keyboards.
- the switch contact of the well-known snap disk switch is regularly in the highest point of the curvature arranged.
- click on the bulge Exerted pressure causing it to bend or snap inwards and the switching contact strikes a counter contact.
- the contact path of conventional snap disk switches is about 0.3 to 1 millimeter. As a result, this is in the low voltage range a safe separation of the contacts is achieved, for higher voltages the However, do not use known snap disk switches. In particular let the well-known snap disk switches do not use for power disconnection, because 2.5 to 3 millimeters switching travel are required for a mains disconnection function.
- a separating element is provided, by means of which at least one Support element, via which the snap disk is supported on a base element is at a distance from the base element. Because through the separating element at least one support element is lifted off the base element, too the curvature of the snap disc moves away from the base element. This increases the distance of the contact arranged at the highest point of the curvature to the mating contact, which is usually attached to the base element.
- the Support element is preferably at such a distance by the separating element brought from the basic element that the distance between the two contacts at least Is 3 millimeters. This allows the snap disk switch to Use grid separation.
- the separating element is as one leaf spring extending from a support element.
- the separating element can be particularly easy to manufacture.
- Leaf springs are located, which in the relaxed state the support elements from Place the basic element at a distance.
- leaf springs instead of leaf springs, however, others could elastic elements such as coil springs can be used when this should be appropriate.
- the separating element has a plug-in foot, by means of which it can be fastened in an opening.
- the plug-in foot is designed in a particularly advantageous manner as a bent sheet metal part. Hereby it is particularly easy to manufacture.
- the separating element and thus the snap disc can be opened by means of the plug-in foot attach in a particularly simple manner, for example on a circuit board, wherein the attachment offers a wobble-free fit.
- the wobble-free fit is special important, since a loose fit of the plug-in foot would result in the Snap disc does not remain in a fixed position but has a game. The game would, however, increase the distance between the two contacts change.
- the attachment of the separating element can still be improved in that a Fastening tab is provided, by means of which it can be fastened.
- the fastening tab has an opening with which it can, for example, on a PCB can be screwed.
- the mounting bracket it is also possible to use the mounting bracket to solder. This also applies to the plug-in foot.
- the snap disc is integrally formed. That is, the domed snap disk, the leaf spring-shaped Separating element and the plug-in foot designed as a bent sheet metal part as well as the mounting bracket are made from a sheet metal part by punching, embossing and bending.
- a snap disk switch has a curved one Snap disc 1, which at the highest point of its curvature Has switching contact 2.
- the switch contact 2 is surrounded by a circular bead.
- the snap disc 1 is circular in plan view, wherein four feet 3, 4, 5, 6 extend outwards at their edge. Feet 3, 4, 5, 6 are slightly bent at their end facing away from the snap disk 1, whereby they form support elements, by means of which the snap disc 1 on a Base element 7 is supported, as can be seen in particular from FIG. 4 can.
- the snap disk switch has a mating contact 2 ', which is opposite the switching contact 2 is arranged and on which the switch contact 2 in the actuated state of the snap disc 1 rests.
- a separating element 8 designed as a leaf spring closes on two feet 5, 6 on.
- the separating element 8 is in one piece with the feet 5, 6 and the snap disc 1 trained and practically represents an extension of the feet 5, 6 the separating element 8 from two sections, which have identical leaf springs are.
- the separating element 8 is bent at the end. The turn is so strong that it turns on the base element 7 resting feet 3, 4, 5, 6 approximately perpendicular to the plane of the Basic element 7 runs.
- the plug-in foot 9 is a bent sheet metal part and formed in one piece with the separating element 8.
- the separating element 8 On his feet 5, 6 and the snap disk 1 facing away At the end, the separating element 8 also has a fastening tab 10.
- the Fastening tab 10 is circular and has an opening 11.
- the retaining tab 10 is a continuation of the leaf spring Separating element 8 and integrally formed with this.
- the snap disk switch is formed so that the plane of the points with which the support elements in confirmed state of the snap disc lie on the base element in a relaxed state Condition, an angle of about 15 ° to the level of the retaining tab having.
- the support elements 3, 4, 5, 6 are at a distance from the base element 7. This causes the distance of the switching contact 2 from the counter contact 2 'larger than it would be in the case if the support elements 3, 4, 5, 6 on the base element 7. Due to the increased switching path the snap disk switch is therefore suitable for a mains disconnection function.
