Description

Technical Field

[0001] The utility model relates to the technical field of microswitches, in particular to a microswitch for automotive parts. Background Technique

[0002] A microswitch is a contact mechanism with a tiny contact interval and a quick-acting mechanism, which performs switch actions with a specified stroke and a specified force, is covered with a housing, and has a driving rod on the outside. Because the contact spacing of its switch is relatively small, it is called a microswitch, also known as a sensitive switch. An external mechanical force acts on the action reed through a transmission element. When the action reed displaces to the critical point, an instantaneous action occurs, causing the moving contact at the end of the action reed to quickly connect or disconnect from the fixed contact. The internal structure of traditional microswitches is complex and requires multiple fittings to complete the connection or disconnection, which is very inconvenient in production. Content of the Utility Model

When pressed, it pushes the rotor 4 to move, and contacts the fourth installation hole 15 through the inclined surface on one side of the second protrusion 18, realizing the function of rotating the rotor 4, such as the telescopic structure of a push-button ballpoint pen.

[0030] A support surface 17 is provided at the top of the rotor 4 for placing and supporting the small spring 3. A second installation groove 19 is opened at the bottom of the rotor 4 for installing the large spring 5. A third protrusion 20 is provided in the second installation groove 19. A hollow sleeve is provided on the terminal 6, and a fifth installation hole is opened on the sleeve to cooperate with the third protrusion 20 to fix the terminal 6. A limit rib 21 is fixedly connected to the bottom of the terminal 6 to cooperate with the sixth installation hole 22 opened on the conducting piece 7 to fix the terminal 6.

[0031] A through hole 24 is opened on the conducting piece 7 to cooperate with the fixing block 29 provided on the conducting plate 9 to fix the conducting piece 7.

There are three contact pieces 8 on the internal conduction plate 7. During the pressing and rotating process, the conduction piece 7 rotates following the rotation of the rotor 4, and the lapping claws 23 also rotate together. During the rotation, they cooperate with the contact piece 8 installed on the conduction plate 9, and staggeredly lap to achieve a conversion of the circuit. During the rotation of the lapping claws 23, the initial state is to lap with a and b in the contact piece, realizing that circuit 2 consumes the circuit and is in a closed state without any response at this time. When the rubber handle 2 is pressed and rotated, the internal structure also rotates together, driving the rotation of the lapping claws 23 on the conduction piece 7, changing from the original lapping of a and b metal sheets to the lapping of b and c metal sheets, thereby achieving a conversion of a circuit and switching to the used circuit, and circulating in this way.
