Description

Technical Field

[0001] The utility model relates to the technical field of light touch switches, in particular to a light touch switch with high stability. Background Art

[0002] A tact switch is an electronic switch that typically switches a circuit on or off by gently pressing the operating handle. A tact switch typically contains an elastic metal sheet or conductive rubber. When an external force presses the switch's operating handle, the metal sheet or rubber deforms, making contact with the contacts and thus completing the circuit. When the external force disappears, the switch returns to its original state due to its internal elastic restoring force, disconnecting the circuit.

[0003] However, since the existing touch switch does not have a structure to limit the elastic metal sheet, the elastic metal sheet is prone to vibration when rebounding, causing the position of the elastic metal sheet to shift, thereby causing the contact between the elastic metal sheet and the contact to shift and cause poor contact, resulting in low stability in the use of the touch switch.

A spring 6 is provided on the top of the conductive member 5. The spring 6 is made of metal. A button 7 is provided on the top of the spring 6. By pressing the button 7, the button 7 presses the spring 6. An inner groove 8 is provided on both side walls of the accommodating cavity 4. The limiting mechanism 2 includes a fixing seat 9, which is embedded in the side wall of the inner groove 8. The fixing seat 9 is used to fix the limiting mechanism 2. A limiting plate is provided on the fixing seat 9 through a pin hinge. 10. A torsion spring 11 is sleeved on the pin shaft to provide elastic force for the limit plate 10 through the torsion spring 11. A stop block 12 is provided on one side of the bottom surface of the limit plate 10. The stop block 12 abuts against the top edge of the spring piece 6. The spring piece 6 is abutted and limited by the limit plate and the stop block 12. Through the cooperation between the limit plate 10, the torsion spring 11 and the fixing seat 9, while limiting the spring piece 6, the elastic force generated when the spring piece 6 rebounds can also be buffered, further weakening the vibration of the spring piece 6 when it rebounds, thereby avoiding the vibration when the spring piece 6 rebounds, which causes the position of the spring piece 6 to be offset and causes poor contact, thereby improving the stability of the touch switch.

When the button 7 is pressed, the spring 6 will deform and contact the contact 2, thereby conducting the circuit.

[0026] In this embodiment, a limiting groove 19 is provided on the top surface of the limiting plate 10, and the two ends of the torsion spring 11 are respectively in contact with the limiting groove 19 and the fixing seat 9.
