The magnetic member is movably disposed in the housing. The magnetic direction detection device is fixed and disposed in the housing to correspond to the magnetic device, and is connected with the power line of the electric appliance such that the magnetic direction detection device makes the power line of the electric appliance form an open circuit when the magnetic device moves relative to the magnetic direction detection device. Therefore, when the electric appliance shakes and tilts, the magnetic member moves relative to the magnetic direction inspection device such that the magnetic direction detection device makes the power line of the electric appliance form an open circuit, so as to protect the electric appliance.

Description

1224348 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention is a power-off protection switch, which is applied to electrical appliances, especially a protection switch that powers off electrical appliances when the electrical appliances are shaken and dumped. [Previous technology] Because electrical appliances are suddenly impacted and dumped in the running state, they may cause damage and become unusable. For example, when the computer is in the running state and suddenly impacted and dumped, it will cause damage to the optical disc or The hard disk is scratched and unusable. Therefore, if the power can be cut off immediately when the electrical appliances are dumped, the electrical appliances can be protected without damaging the electrical appliances. At present, there are two types of power-off protection switches on the market. One is a contact-type power-off protection switch, which is mainly provided by a spring in the switch. When the electrical appliance is normally placed, the switch will be pressed by the placement surface. It is completely placed inside the electrical appliance, and the spring will be compressed. Once the electrical appliance is knocked down due to the impact, the spring will return to normal. At this time, the switch protrudes from the outside of the electrical appliance to power off the electrical appliance, but on the placement surface When the surface is uneven or there are many recesses on the placement surface, the switch may not be completely placed inside the electrical appliance, so that the electrical appliance is powered off and cannot be used. Another type of non-contact power-off protection switch is mainly through a container provided with pins around and containing mercury and metal balls inside. When the electrical appliances are dumped, the power will be cut off to protect the electrical appliances. Therefore, when the electrical appliance is normally placed, the metal ball will be located in the container without touching the pins. Once the electrical appliance is knocked down due to the impact, the metal ball will also contact the pins to power off the electrical appliances. When the surface is uneven, the metal ball also

2. Description of the invention (2) Will touch the pins, Summary of content] The main thing of this creation is the shaking of the supplies. According to this creation, it includes a shell, in which the magnetic parts are fixed to the magnetic parts, and the magnetic parts are used to make electrical appliances. When it is placed, the magnetic square road is' but when the electrical appliance moves to the detection part, the road becomes open circuit. According to the original work, it includes the following: 1. The invention can have a wide range of applications 2. The invention of the invention 3. The department of the invention The limitation of the placement surface is to make you aware of the original product, and it is hereby combined with the diagram. [Embodiment] Therefore, when the electrical appliance is used in the power-off method, the use of electrical parts should be reversed. The line-direction detection supplies are shaken, so the effects disclosed by the magnetic pair of electrical appliances are applied to the level. The use is non-connected, and the detailed visual indication is to provide a pair of electrical appliances with power-off protection ^ One piece is installed in the housing, and the circuit with the electrical direction detection device becomes a disconnection piece, which causes the electrical appliance to fall. , Sexual orientation detection supplies are protected by power failure protection. The opening magnet should be above the magnet and magnetic equipment when moving. Therefore, the magnetic parts of the power supply of the in-process product make the electrical protection switch for electrical direction detection. It is applied to the ports and components of electrical appliances such as computers, appliances, and locomotives, etc., with a constant open line relationship at the η continuous test, and its cost is low. The contact type, so it will not be affected by the direction and induction angle, the structural features and their functions are described below: Limitations of electrical appliances.

V. Description of the invention (4) The cost is low, so considerable cost can be saved. Furthermore, because the present invention is a non-contact power-off protection switch, there is no restriction on the placement surface of electrical appliances, and Limited by direction and sensing angle.

As shown in the "Figure 4", the present invention can be further designed with an elastic element 50, which is disposed on the lower edge of the magnetic direction detecting member 30, and can just abut the cover 40, and each elastic element The included angle between 50 is the same, so that when the electrical appliance is touched by mistake, the elastic element 50 absorbs the oscillating force, so the magnetic direction detecting member 30 will not change its relative relationship with the magnetic member 20, of course. As shown in "Figure 5", the aforementioned elastic element 50 can also be disposed on the cover body 40, and can just abut the magnetic direction detecting member 30, and the angle between each elastic element 50 is also the same. The above are only the preferred embodiments of this creation, and are not intended to limit the scope of implementation of this creation; that is, all equivalent changes and modifications made in accordance with the scope of the patent application for this creation are covered by the scope of this creation patent .
