PROBLEM TO BE SOLVED: To provide a multidirectional push-switch with a reduced thickness, having a key-top capable of smoothly performing a swinging operation. SOLUTION: The multidirectional push-switch comprises a switch contact forming member 10 having reversible plates 27 each located on a plurality of switch contacts 28, a jointing member 30 composed of a base part 31 located at the center of the plurality of reversible plates 27 on the switch contact forming member 10 and hinges 39 extending from the base part 31, and the key-top 50 arranged on the jointing member 30. Pushing parts 53 are formed on the key-top 50 at the parts facing the respective switch contacts 28. The switch contact 28 is turned on by reversing the reversible plate 27 facing the pushing part 53 pushed down by pushing the key-top 50. A convex-shaped supporting part 33 is formed on an upper surface of the base part 31 of the jointing member 30, and a concave-shaped support receiving part 51 is formed at the center of the lower surface of the key-top 50, and the key-top 50 is supported on the base part 31 in free swinging movement by fitting the supporting part 33 to the support receiving part 51.
