The action mode of the waterproof button switch is as follows: when the button is not operated, the movable contact piece is not connected with the static contact piece, and the button switch is in a disconnected state; when operating button pushed down, the second spring was compressed, and the stopper plays the guide effect in the action of stroke spout, and the movable contact on the button forms the electricity with the static contact on the base to be connected, and first spring provides the overtravel effect for the movable contact and makes it can be connected with the static contact stability, and the return circuit that constitutes button switch switches on, looses behind the button under the effect of second spring, and the button resets to initial height, and the movable contact separates with the static contact. The utility model discloses button switch inner structure sets up to connect stably, the action is reliable between compact, the spare part to cover the base with the buckler, make button switch's barrier propterty obtain promoting.

This practicality further sets up to the upper end and the lower extreme in hole groove all form the dog, the dog sets up the upper and lower both sides at the contact site.

The utility model discloses further set up to the static contact and be provided with two, the contact site forms two movable contacts by one side of static contact, the movable contact pushes down along with the button and forms the connection with the static contact that corresponds respectively.

The stop block can limit the moving of the movable contact piece in the vertical direction of the button, prevent the movable contact piece from being deviated to cause the failure of normal connection with the static contact piece, and further improve the reliability of electric connection when the button switch acts.
