To provide a switch mechanism of electronic equipment with small number of components, low cost, and having an excellent operation feeling.

The switch mechanism of the electronic equipment has a switch spring 32 and a regulating part 36 which is engaged with a tip part 33 of the switch spring 32 and regulates a bending direction position of the switch spring constructed in one body with a switch plate 30a continuing from the base part 31 of the switch spring 32. The switch spring 32 has an action part 35 installed in the middle of the base part 31 and the tip part 33 of the switch spring 32 and a connecting part 34 with a circuit terminal part 51 installed in the middle of the tip part 33 and the action part 35. The connecting part 34 is connected to the circuit terminal part 51 by energizing a pushing force of the action part 35 in the direction of the circuit terminal part 51 and releasing engagement of the regulating part 36 and the tip part 33, and when the pushing force of the action part 35 is released, connection of the circuit terminal part 51 and the connecting part 34 is released by the elasticity of the switch spring 32 and the switch spring 32 is returned to an initial position before it is energized by the pushing force.
