It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

Please refer to fig. 1 to 3, which are preferred embodiments of the present invention, a button switch in the present embodiment includes a housing 1, a receiving space 2 is provided inside the housing 1, a rubber base 3 is movably provided in the receiving space 2, an installation space 4 is provided on the rubber base 3, three pairs of pins 5 are provided in the installation space 4, the three pairs of pins 5 extend out of the housing 1, a connecting piece 6 is provided between the pins 5 and the bottom wall of the installation space 4, and the rubber base 3 reciprocates in the receiving space 2 to drive the connecting piece 6 to electrically connect a pair of pins 5 located at a middle position and any one pair of pins 5 respectively located at two sides thereof.

Referring to fig. 2 and 3, the rubber base 3 extends out of the housing 1 to form a rubber head 7, and the rubber head 7 is pushed to control the reciprocating motion of the rubber base 3 in the accommodating space 2. The rubber head 7 is provided with a protrusion 8, a buckling piece 9 is sleeved at the protrusion 8, a spring 10 is tightly propped between the buckling piece 9 and the shell 1, and the rubber head 7 is sleeved with the spring 10. When the glue head 7 is pressed to extend into the accommodating space 2, the electric connection between the pin 5 at the middle position and the pin 5 at the inner side can be realized; when the pin is released, the rubber head 7 is reset under the action of the spring 10, and the pin 5 at the middle position is electrically connected with the pin 5 at the outer side.
