AI Technical Summary
In existing push-button switches, poor contact is prone to occur between the end of the conductive spring and the first or second electrode, leading to intermittent connection, overheating, and damage to the push-button switch.
An upwardly extending boss is provided on the sidewalls of both ends of the conductive spring. A top block corresponding to the boss is provided at the lower end of the movable block. When the button is turned, the top block alternately abuts against the inner side of the boss, so that the two ends of the conductive spring reliably abut against the first electrode and the second electrode respectively and make contact with the conductor.
This avoids poor contact between the end of the conductive spring and the electrode, prevents overheating from intermittent connections, and extends the service life of the push-button switch.
