Description

Technical Field

[0001] This utility model belongs to the field of switches, and in particular relates to a high-power metal push button switch. Background Technology

[0002] High-power metal push-button switches are electrical switches that combine a metal housing with a high-power tactile switch. Designed for high load currents, they feature high strength and corrosion resistance, making them suitable for industrial and other specialized applications. The traditional high-power metal push-button switch structure includes a base, a metal housing outside the base, and a push-button assembly on top of the base, with the high-power tactile switch located at the bottom. The drawbacks are that the push-button assembly directly triggers the high-power tactile switch via a push rod, resulting in poor stability and high resistance. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a high-power metal push-button switch with good stability and low resistance.

[0004] To solve the above problems, the technical solution adopted by this utility model includes: a base, a metal shell disposed outside the base, and a button assembly disposed on the upper end of the base. A high-power tactile switch is provided at the lower end of the base. The button assembly includes a button cap, a sliding frame, and a pressure plate. The button cap is installed on the upper end of the sliding frame. The pressure plate is slidably installed in the pressure plate groove at the upper end of the base. Side plates are provided on both sides of the sliding frame. At least two first protruding ribs are provided at the bottom of the side plates to abut against the pressure plate. The bottom of the pressure plate is provided with a protrusion to abut against the button of the high-power tactile switch.

[0005] The high-power tactile switch includes a base, a top cover, and a contact mechanism disposed within the base and top cover. The contact mechanism includes a normally closed pin, a normally open pin, a moving contact bracket, a button, a large spring, and small springs. The normally closed pin and the normally open pin are a pair, respectively disposed at both ends of the base, with a stationary contact disposed opposite to each other between them. The moving contact bracket is disposed between the normally closed pin and the normally open pin, and has moving contacts at both ends that cooperate with the stationary contacts for switching on and off. The button is disposed in the middle of the moving contact bracket. The large spring is disposed between the base and the button. The two small springs are disposed opposite to each other between the moving contact bracket and the button, and are arranged in a figure-eight shape.

[0006] The upper end of the base is provided with a side plate groove that is adapted to the side plate.

[0007] The sliding frame is provided with first hooks at both ends, and the upper end of the base is provided with a bushing, the bushing being provided with a long groove that mates with the first hooks.

[0008] The side plate is provided with a self-locking groove.

[0009] A conical sealing ring is provided between the bushing and the button.

[0010] The base has a second hook on both sides that connects to the base.

[0011] The base is provided with a long support column and a short support column. The upper end of the normally open pin is mounted on the long support column, and the upper end of the normally closed pin is mounted on the short support column.

[0012] The button has a first spring positioning part and a bracket positioning groove inside, and a second spring positioning part at the lower end. The moving contact bracket has a spring relief groove in the middle and positioning plates on both sides. The spring relief groove has a third spring positioning part at both ends.

[0013] The advantages of this high-power metal push button switch are as follows: the button assembly uses a combination of a push cap, a sliding bracket and a pressure plate to press the button of the high-power tactile switch, and raised ribs and raised dots are respectively set on the contact surface, making the pressing more stable and smooth.

[0014] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

A high-power tactile switch 4 is disposed at the lower end of the base 1. The button assembly 3 includes a button cap 5, a sliding frame 6, and a pressure plate 7. The button cap 5 is installed on the upper end of the sliding frame 6, and the button cap 5 is usually connected to the third hook 39 of the inner ring of the sliding frame 6 through a hanging hole 38. The pressure plate 7 is slidably installed in the pressure plate groove 8 at the upper end of the base 1. Side plates 9 are provided on both sides of the sliding frame 6. The bottom of the side plates 9 is provided with two first protruding ribs 10 that abut against the pressure plate 7. The bottom of the pressure plate 7 is provided with a protrusion 12 that abuts against the button 11 of the high-power tactile switch 4.

[0027] Preferably, the high-power tactile switch 4 includes a base 13, a top cover 14, and a contact mechanism 15 disposed within the base 13 and the top cover 14. The contact mechanism 15 includes a normally closed pin 16, a normally open pin 17, a moving contact support 18, a button 11, a large spring 19, and small springs 20. The normally closed pin 16 and the normally open pin 17 are respectively disposed at both ends of the base 13, and a stationary contact 21 is disposed opposite to each other between them. The moving contact support 18 is disposed between the normally closed pin 16 and the normally open pin 17, and both ends are provided with moving contacts 22 that cooperate with the stationary contacts 21 for switching on and off. The button 11 is disposed in the middle of the moving contact support 18. The large spring 19 is disposed between the base 13 and the button 11. Two small springs 20 are disposed opposite to each other between the moving contact support 18 and the button 11, and are arranged in a figure-eight shape. The elastic force of the large spring 19 is greater than the sum of the elastic forces of the two small springs 20. In the reset state, the large spring 19 pushes the button 11 upward, causing the inner end of the small spring 20 to face upward. The outer end of the small spring 20 then presses down the moving contact support 18, causing the moving contact 22 to close with the stationary contact 21 on the normally closed pin 16. When the user pushes the button 11 downward, the inner end of the small spring 20 faces downward, causing the outer end of the small spring 20 to press up the moving contact support 18, causing the moving contact 22 to close with the stationary contact 21 on the normally open pin 17.
