The embodiment of the present invention relates to a button switch, which includes a button sleeve (11), a button (12) movably accommodated in the button sleeve (11) in a button moving direction, a locking member (13) movable linearly between a first position and a second position relative to the button (12), and a drive member (14) configured to switch on/off states of the button switch in response to the button (12) being pressed from an initial position. The locking member (13) is configured to be driven by the driving member (14) to linearly move to a first position or a second position. When the button (12) is released, the locking member (13) locks the button (12) in a resting position that is lowered in height relative to the initial position of the button (12) in the first position, and the locking member (13) unlocks the button (12) in the second position to allow the button (12) to return to the initial position. The button switch of the invention indicates the on-off state of the switch through the height position of the button, so that the state indication of the switch is more direct.
