The present invention relates to a dome switch which has a simplified structure including a button activated by a user, an actuator, which is operated by the button and generates an input signal using a switch contact, and an elastic member which pushes the actuator and the button to original positions, which are integrated in the simplified structure to improve economic feasibility. The dome switch having a button unit pressed by a user, an actuating unit which comes into contact with a contact point (3) of a printed circuit board (PCB) (2) according to the movement of the button unit and generates a signal, and an elastic unit which applies an elastic force such that the actuating unit returns to an original position, comprises: an input bump (7) which is arranged at a center of a ring-type body (4) arranged on a surface where the contact point (3) of the PCB (2) is disposed, and moves in a pressed direction, when pressure is applied, to configure the button unit; a connecting band (9) which connects an inner circumferential surface of the body (4) with the input bump (7) and includes an elastic pattern unit (8) to configure the elastic unit by including elasticity; and a movable bump (10) which is provided on the connecting band (9) and touches the contact point of the PCB (2), when the input bump (7) moves, to generate a signal. The body (4), the input bump (7), the connecting band (9), and the movable bump (10) are formed in one entity through an injection molding process. |
