Description

Technical Field

[0001] This utility model relates to the field of switch technology, and in particular to an integrated plastic-coated waterproof Hall effect switch. Background Technology

[0002] Existing microswitches generally use metal clips to switch circuits on and off. During operation, these clips are prone to contact instability due to vibration or assembly errors, posing a risk of intermittent disconnection. During assembly, the metal clips are easily deformed by external forces, causing electrical parameter drift and affecting switch consistency. Furthermore, these switches rely on physical contact for conduction, and long-term use inevitably leads to problems such as mechanical component wear, contact oxidation, and electrical spark erosion, typically limiting their lifespan to tens of thousands to hundreds of thousands of cycles. Regarding waterproofing, insufficient sealing design allows dust and moisture intrusion, exacerbating poor contact and further reducing switch reliability, making it difficult to meet the long-term stable operation requirements of harsh conditions such as automotive engine compartments and outdoor equipment. Utility Model Content

[0003] The purpose of this invention is to provide an integrated plastic-coated waterproof Hall effect switch with a longer service life.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A one-piece plastic-coated Hall effect waterproof switch includes a housing, a push button, and a sealing ring disposed between the housing and the push button, and further includes: A base, wherein the base is provided with protrusions for mounting elastic elements; A Hall element, wherein the Hall element is disposed on the base and is integrally encapsulated with the base; A magnet is disposed on the button and positioned above the Hall element; An elastic element, with one end sleeved on the protrusion and the other end abutting against the bottom of the button, is used to provide a restoring elastic force when the button is pressed down.

[0005] Furthermore, the button includes a vertical pressing block and a horizontal connecting block, and the connecting block has a groove for accommodating the magnet at one end near the Hall element.

[0006] Furthermore, the bottom of the connecting block is provided with a circular groove for installing the elastic element.

[0007] Furthermore, the Hall element is connected to a terminal block that passes through the base.

[0008] Furthermore, the elastic element is a spring.

[0009] Furthermore, the base is installed inside the housing and a sealed structure is formed by applying adhesive.

[0010] Furthermore, after the sealing ring is installed into the outer shell, a sealing structure is formed by a hot riveting process.

[0011] Furthermore, the Hall element is encapsulated with an epoxy resin encapsulation layer.

[0012] Furthermore, the pressing block and the connecting block of the push button have an L-shaped integrated structure.

[0013] This utility model's switch base uses a Hall element, with a magnet mounted on the button. Pressing the button changes the relative position of the magnet and the Hall element, causing a change in magnetic flux and thus outputting a switch on / off signal. This non-contact sensing structure fundamentally avoids the risk of flickering in traditional switches, resulting in more stable parameters. Since it has no internal mechanical contacts, its lifespan depends primarily on the Hall element itself, reaching millions of operations, far exceeding that of traditional mechanical switches. The Hall element is completely encapsulated in epoxy resin, and combined with the sealed housing design, it achieves an IP67 or higher protection rating, easily coping with dust, water splashes, oil stains, vibration, and temperature fluctuations inside the car, exhibiting stable performance in harsh environments such as the engine compartment and chassis.
