Embodiment Construction

[0009] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0010] Such as figure 1 As shown in the movable (normally open) magnetic button, the permanent magnet 1 is inlaid on the lower end of the plastic insulating touch column 6, the permanent magnet 2 is inlaid on the bottom of the inner cavity of the plastic insulating shell 7, and the opposite ends of the permanent magnet 1 and the permanent magnet 2 are It is the same pole (the same as the N pole or the same as the S pole), the conductive movable contact 3 with contacts at both ends is embedded in the middle of the touch column 6, the conductive fixed contact 4 and the conductive fixed contact 5 are embedded in the plastic Insulation housing 7.

[0011] Its working principle is: the touch column 6 is close to the upper part of the inner cavity of the shell 7 under the action of the same polarity of the permanent magnet 1 and the permanent magnet 2, and when th...

Abstract

The invention provides a magnetic button which can achieve structural simplification and integral attenuation. Two permanent magnets are embedded in an outer shell and a touch column respectively, a movable contact is fixed to the touch column, a fixed contact is fixed to the outer shell, and under the mutual action of the two permanent magnets and the action of pressing the button externally, the touch column drives the movable contact to be connected or disconnected with the fixed contact in an outer shell moving chamber. The connection and the disconnection of a switch are controlled by pressing the button, and when the button is released, the switch is reset immediately through the action of force generated by the repellent of the same poles or the attraction of the opposite poles between the two permanent magnets. According to the relation of the force of the repellent of the same poles and the force of the attraction of the opposite poles between the two permanent magnets and a distance, the shorter the distance is, the larger the force is, and the longer the distance is, the smaller the force is. The magnetic touch switch can be connected by gradually increasing the force of pressing the button when the magnetic touch switch is dynamically connected, the force of pressing the button needs to overcome larger force at the very start so that the switch can be dynamically disconnected, and therefore the effective reliability of dynamically connecting and disconnecting the switch can be guaranteed.

Description

technical field [0001] The invention relates to a moving-on (normally open) or moving-off (normally closed) button for contacting or disconnecting a movable contact with a fixed contact by pressing, in particular to a magnetic button for small and medium-sized electrical equipment. technical background [0002] At present, the button generally uses a spring return structure. To obtain a large return elastic force, a large inner cavity volume is required, and the structure is relatively complicated. Contents of the invention [0003] The purpose of the present invention is to provide a new material permanent magnet to manufacture buttons, utilize the principle that the same poles repel each other and different poles attract each other between two magnets, and combine with the force principle of the dynamic closing and dynamic breaking touch switches, By using different materials to achieve the same purpose, develop beneficial applications of different materials, and develop...
