PROBLEM TO BE SOLVED: To provide a switch button structure easily confirming an operation status of a recording switch by observing it with eyes and touching it with a hand. SOLUTION: The switch button structure is composed of a recording button 10' reciprocating between a press-operation state in which an arc part 10c presses a recording switch 11' to make it an on state because an operation part 10a is pressed and operated and a return state in which the recording switch 11' is returned from the press-operation state and its on state is released; a tensile coil spring 29 energizing the recording button 10' into a direction returning from the press-operation state to a return state; a rod 34 of which one end part is locked into the other end part of the recording button 10'; and a solenoid plunger 30' having a permanent magnet 33, a core 32 guiding magnetic force of the magnet 33 and a solenoid coil 31 generating magnetic force suppressing the magnetic force guided by the core 32, absorbing the other end part of the rod 34 to the core 32 by press-operating the recording button 10' and holding the absorption after releasing the depression-operation.
