PROBLEM TO BE SOLVED: To provide a tactile switch so made to effectively prevent such an unjust act as altering a bonus appearance probability properly set at a hall side, even in the case it is used for a setting change button switch of a slot machine in particular. SOLUTION: The tactile switch 1<SB>1</SB>is so structured that a pressing operation of a first push button 5 is locked with a second push button in a free state, and the first push button 5 can be press operated with the second push button 6 in a press-operated state in an arrow mark B direction. Thus, a situation is realized where the first push button 5 can not be operated unless the second push button 6 is press operated, although a click feeling always accompanies the press operation. Therefore, if it is used as, for instance, a setting change button switch of a slot machine, an unjust act by an unjust actor can be effectively inhibited. COPYRIGHT: (C)2007,JPO&INPIT
