PURPOSE: A PCB type tact switch is provided to achieve improved reliability by preventing error of electrical signal and fault caused due to foreign substance and moisture, while reducing weight and size of the switch. CONSTITUTION: A PCB type tact switch(100) comprises a PCB(110), and the PCB includes a connection terminal(112) formed at the upper surface of a substrate(111) and which has a central contact section and a variable contact section, and a terminal(113) formed at the bottom surface of the substrate and electrically connected to the central contact section and the variable contact section of the connection terminal. A metal contact(120) for electrically connecting the central contact section and the variable contact section is mounted to the PCB. A seal cover(130) made of an elastic rubber material and which has a press dome(131) covering the metal contact, is compressed, at a high temperature and high pressure, onto the top surface of the PCB, and coupled integrally with the PCB.
