When the self-locking hook 50 is provided, in step S1, the self-locking hook 50 can be hooked on the clasp 16, and at this time, the acting force for pressing the push rod 1 is removed, and the push rod 1 cannot return under the action of the self-locking hook 50; in step S2, the push rod 1 is first pressed to separate the hook 16 from the hook 50, and then the force applied to the push rod 1 is removed to move the push rod 1 upward under the resilience of the stop spring 6
In another possible embodiment, the push-button switch with the socket is set to be in a "two-normally open" structure, and in a default state, the two first static contacts 4 and the two second static contacts 5 are in a power-off state. In step S1, the movable contact 2 in the first mounting portion 111 approaches to the first stationary contact 4, that is, the first contacts 21 at both ends of the movable contact 2 in the first mounting portion 111 are attached to the second contacts 41 of the two first stationary contacts 4, so as to form an energized state; the two second static contact pieces 5 are pressed on the movable contact piece 2 in the second installation part 121, namely, the third contact points 51 of the two second static contact pieces 5 are respectively attached to the first contact points 21 at two ends of the movable contact piece 2 in the second installation part 121 to form an electrified state; in step S2, the push rod 1 moves upward under the resilience force of the stop spring 6, the movable contact 2 in the first mounting portion 111 is separated from the two first stationary contacts 4, and the movable contact 2 in the second mounting portion 121 is separated from the two second stationary contacts 5, so as to restore to the default state.
When the self-locking hook 50 is provided, in step S1, the self-locking hook 50 can be hooked on the clasp 16, and at this time, the acting force for pressing the push rod 1 is removed, and the push rod 1 cannot return under the action of the self-locking hook 50; in step S2, the push rod 1 is first pressed to separate the hook 16 from the hook 50, and then the force applied to the push rod 1 is removed to move the push rod 1 upward under the resilience of the stop spring 6
In yet another possible embodiment, the push-button switch with socket is set to a "two normally closed" configuration, and in the default state, both the first and second stationary contacts 4, 5 are in an energized state. In step S1, the movable contact 2 in the first mounting portion 111 is separated from the first stationary contact 4, that is, the first contacts 21 at two ends of the movable contact 2 in the first mounting portion 111 are separated from the second contacts 41 of the two first stationary contacts 4, so as to form a power-off state; the two second static contacts 5 are separated from the movable contact 2 in the second installation part 121, namely, the third contacts 51 of the two second static contacts 5 are respectively separated from the first contacts 21 at two ends of the movable contact 2 in the second installation part 121, so that a power-off state is formed; in step S2, the push rod 1 moves upward under the resilience force of the stop spring 6, the movable contact 2 in the first mounting portion 111 is attached to the two first stationary contacts 4, and the movable contact 2 in the second mounting portion 121 is attached to the two second stationary contacts 5, so as to restore the default state.
When the self-locking hook 50 is provided, in step S1, the self-locking hook 50 can be hooked on the clasp 16, and at this time, the acting force for pressing the push rod 1 is removed, and the push rod 1 cannot return under the action of the self-locking hook 50; in step S2, the push rod 1 may be pressed first to disengage the hook 16 from the latch hook 50, and then the force pressing on the push rod 1 is removed to move the push rod 1 upwards under the resilience force of the stop spring 6.
The foregoing is illustrative of the present invention and is not to be construed as limiting the scope of the invention. Any equivalent changes and modifications can be made by those skilled in the art without departing from the spirit and principles of this invention, and are intended to be within the scope of this invention.
