PROBLEM TO BE SOLVED: To provide a push switch which prevents residual flux from intruding into a contact part during soldering.SOLUTION: A push switch includes: a housing 10 where a fixed contact member 20 having a fixed contact part 21 is provided; and a cover member 40. A solder part 23 for soldering the fixed contact member 20 to a printed wiring board is provided at the fixed contact member 20. The solder part 23 is disposed at a step part 10b, which is positioned closer to the cover member 40 side than a bottom surface 10a of the housing 10, being exposed. The solder part 23 includes: a first solder surface 23a which is located at the outer side of the housing 10 and is wide; and a second solder surface 23b which is located at the fixed contact part 21 side and is narrower than the first solder surface 23a. The second solder surface 23b is disposed to a border part 10d between a wall surface 10c, which connects the bottom surface 10a with the step surface 10b, and the step surface 10b. |
