[0002] Current door glass lift switches primarily come in three-position and multi-position configurations. These require three or more switches to control the glass lift. These switches occupy multiple positions and are expensive. Multi-position buttons in cars can significantly reduce installation space, enabling multiple functions with a single button, saving space and cost. Summary of the Invention

[0003] In order to save switch installation space and switch cost in the vehicle, the utility model provides a novel three-position push button switch, which provides convenient operation for the driver.

[0004] The utility model is implemented by adopting the following technical scheme: a novel three-speed push button switch, including a shell and a keycap, a buckle is respectively provided on the left and right sides of the shell, a pin panel is provided in the shell, the pin panel includes a first pin, a second pin, a third pin, a fourth pin and a fifth pin, the first pin, the second pin, the third pin, the fourth pin and the fifth pin are all connected with a conductive plate, the first pin, the second pin, the third pin, the fourth pin and the fifth pin are vertically downward, a first contact is provided on the conductive plate of the first pin, two common contacts are provided on the conductive plate of the third pin, and a second contact is provided on the conductive plate of the fourth pin, wherein the first contact and one common contact on the conductive plate of the third pin are located in the first row, the second contact and the other common contact on the conductive plate of the third pin are located in the third row, the end of the conductive plate of the second pin and the end of the conductive plate of the fifth pin are located in the second middle row, and an opening facing upward is provided on the shell. The pin sheath below, the conductive plates of the first pin, the second pin, the third pin, the fourth pin and the fifth pin pass through the pin sheath horizontally and are connected to the pin sheath. After the conductive plate is fixed, the first pin, the second pin, the third pin, the fourth pin and the fifth pin are located in the pin sheath; a contact slot is provided on the shell above the conductive plate, and a baffle is provided in the contact slot to divide the space in the slot into two parts, and contacts are respectively placed in the two slots of the contact slot, and horizontal pressure plates are extended outward at the left and right ends of the contact sheet respectively. A key seat is provided above the contact slot, and hinge shafts are provided on the front and back sides of the key seat. The key cap includes a shell, and hinge shaft holes are provided on the front and back sides of the shell. Two vertical spring tubes are provided in the shell, and springs are respectively provided in the spring tubes. A conical head pressure rod is provided below the spring, and one end of the conical head pressure rod is a conical head, which is inserted into the spring. After the key cap is hingedly installed on the key seat, the other end of the conical head pressure rod presses on the contact sheet.

[0005] After the three-speed push button switch of the utility model is fixedly connected to the car door, in the initial state, the conical head pressure rod in the key cap shell presses on the middle bottom of the contact piece, and the horizontal pressure plates at the left and right ends of the contact piece do not contact the first contact, the common contact, and the second contact. At this time, the push button switch is in one gear state. When the key is pressed down, the key cap swings downward, driving the conical head pressure rod in the key cap to slide on the left side of the surface of the contact piece. When the conical head pressure rod moves to the left side of the contact piece, the horizontal pressure plates at the left ends of the two contact pieces respectively contact the first contact and the common contact. At this time, the push button switch is in another gear state. When the key is lifted, the key cap swings upward, driving the conical head pressure rod in the key cap to slide on the right side of the surface of the contact piece. When the conical head pressure rod moves to the right side of the M-shaped contact piece, the horizontal pressure plate at the right end of the contact piece contacts the second contact and another common contact. At this time, the push button switch is in another gear state.

[0006] The above-mentioned new three-position push button switch is also provided with fixed pins on the conductive plates of the first pin, the third pin and the fourth pin. The fixed pins face vertically upward. After the conductive plate is connected to the pin sleeve, the fixed pins pass vertically through the top of the pin sleeve and are fixed.

[0007] The aforementioned novel three-position pushbutton switch also has a limit plate on the left side of the key base. When the keycap is lifted, the left side of the keycap is blocked by the limit plate, limiting the extent of the keycap's upward movement. When the keycap is pressed down, the right side of the keycap is blocked by the top surface of the housing, limiting the extent of the keycap's downward movement.

[0008] The utility model can realize the control of three gears through a key switch, which saves the installation space of the key in the car and also saves the key installation cost. BRIEF DESCRIPTION OF THE DRAWINGS
