[Problem] To supply a push switch having a good click feeling and allowing the operating sound to be lowered. [Solution] The push switch (1) comprises a mobile contacting member (20) having a dome portion (21a) formed into a dome shape and capable of undergoing an inversion operation accompanying a pushing operation, and a fixed contacting member (10) having a first fixed contacting portion (10a) capable of coming into contact with and separating from the mobile contacting member (20). In the push switch (1), when the operation of pushing the mobile contacting member (20) has started, the operation load necessary for the pushing operation gradually increases. Then, the dome portion (21a) undergoes the inversion operation in order to decrease the operation load, and when the pushing operation is further carried on, the operation load increases again. The push switch (1) is characterized in that the dome portion (21a) comes into contact with the first fixed contacting portion (10a) once past an inflection point at which the operation load turns from decreasing to increasing. |
