A switch with a good hand feeling comprising a top cover (1), a base (2), a fixed terminal (3), a movable terminal (4) and a press piece (5). A guide post (21) is disposed on the base, and the press piece is installed on the guide post with a reset spring (8) sleeved thereon. The top cover of the upper end of the press piece is exposed to be pressed. A cavity is formed by buckling the top cover and the base. The fixed terminal and the movable terminal are disposed on a side of the press piece in the cavity. One end of the fixed terminal and one end of the movable terminal both extend out of the base to connect to an external circuit. An upward and downward movement of the press piece drives the movable terminal to move, so as to control the connection and disconnection between the movable terminal and the fixed terminal. A tactile dome (6) is disposed on the other side of the press piece, and protruding ribs (53) are disposed on a corresponding side surface of the press piece. The upward and downward movement of the press piece drives the movable terminal to move, so that the protruding ribs press the dome to improve the pressing touch. The switch further comprises a key indicator (7) disposed on the base. By adding the tactile dome inside the switch, the switch has a good hand feeling. In addition, the switch has a simple structure, and lasts longer. |
