Abstract
The utility model provides a contactless sealed switch which comprises a switch box. A rubber button is arranged on the upper portion of the switch box, a circuit board is arranged in the switch box, a magnet is arranged in the middle of the rubber button, and a Hall element or a reed switch used with the magnet is arranged below the circuit board. The contactless sealed switch can be completely isolated from water by the aid of the working mode of the magnet and the Hall element, solves the problem that a contact switch cannot be sealed due to an open-type working mode, devices needing isolation and sealing are effectively sealed, and the contactless sealed switch has advantages of simple structure, fine sealing performance and the like.
Description
Technical field
The utility model relates to a kind of switch, relates in particular to a kind of enclosed switch.
Background technology
Existing enclosed switch mostly is the contact seal switch, this contact seal switch, contact hole must be set, because the existence of contact hole, make enclosed switch be difficult to realize thoroughly sealing, do not mentionlet alone to be installed in the water and infiltrated by water easily, affect the useful life of switch, just be mounted in and infiltrated by airborne moisture, and affect its useful life.
The utility model content
The purpose of this utility model is exactly the contactless enclosed switch that a kind of good seal performance is provided for above-mentioned situation.The purpose of this utility model can realize by following scheme: a kind of contactless enclosed switch, comprise switch enclosure, the top of switch enclosure is provided with rubber key, the switch enclosure the inside is provided with wiring board, the middle part of rubber key is provided with magnet, be provided with the Hall element or the tongue tube that match and use with magnet below the wiring board, the utility model adopt the working method of magnet and Hall element (or tongue tube) can be fully and water isolate, solved touch switch because the defective that can not seal that the open type working method is brought, making needs the device of isolating seal to be well solved, have the characteristics such as simple in structure, good seal performance.
Description of drawings
Fig. 1, the utility model structural representation.
Embodiment
Contrast Fig. 1 as can be known, a kind of contactless enclosed switch comprises switch enclosure 3, the top of switch enclosure 3 is provided with rubber key 1, switch enclosure 3 the insides are provided with wiring board 4, and the middle part of rubber key 1 is provided with magnet 2, are provided with the Hall element 5 that matches and use with magnet 2 below the wiring board 4.
Above-described embodiment can not limit protection range of the present utility model, can substitute the combination of adopting magnet and Hall element as adopting the working methods such as metal material and metal inductive pick-up.
