PROBLEM TO BE SOLVED: To provide a rubber switch making it possible to use one block key for performing complicated operations such as key inputting in adjoining directions and in confronting positions in addition to individual operations in respective directions, in the case of a multidirectional input switch used for measuring apparatuses and the like. SOLUTION: This rubber switch is made up by forming a plurality of contact circuits 12 on a printed circuit board 2 and placing, on the printed circuit board 2, a rubber sheet 1 integrally formed with a multidirectional input key 3 having, on its back surface, movable contacts 13 corresponding to the contact circuits 12. The multidirectional input key 3 is formed so as to have a thin-walled part provided on its periphery for producing an operation feel at the time of depressing, and the key 3 is divided into respective directional input keys by cutting therein a plurality of radial division grooves not connected to each other in the middle part and corresponding to the respective input directions, a key support part 8 projecting beyond all the movable contacts 13 of the directional input keys is suspended from a middle part on the printed circuit board 2 side of the multidirectional input key 3, and a groove part reaching near an upper surface part of the multidirectional input key 3 is cut in the circumference of the key support part 8.
