A switch apparatus includes a push button switch having a shaft portion and a rotary switch having a rotation operating portion which rotates about the shaft portion of the push button switch. The switch also includes a push button switch contact member and a rotary switch contact member. The push button switch contact member is actuated in accordance with a movement of the shaft portion of the push button switch. The rotary switch contact member is actuated in accordance with rotation of the rotation operating portion. The push button contact member and the rotary switch contact member are spaced from one another along the shaft portion of the push button switch.

DETAILED DESCRIPTION It is an object of the present invention to reduce the surface area or space necessary to mount or provide the push button switch and the rotary switch coaxial thereto.
To achieve the object mentioned above, according to the present invention, there is provided a switch apparatus including a push button switch having a shaft portion and a rotary switch having a rotation operating portion which rotates about the shaft portion of the push button switch.
The switch apparatus includes a push button switch contact member and a rotary switch contact member.
The push button switch contact member is actuated in accordance with a movement of the shaft portion of the push button switch.
The rotary switch contact member is actuated in accordance with a rotation of the rotation operating portion.
The push button contact member and the rotary switch contact member are spaced from one another along the shaft portion of the push button switch.
With this arrangement, since the push button switch and the rotary switch are aligned along the same axis and the contact members of the push button switch and the rotary switch are superimposed along the axis of the shaft portion of the push button switch, the mounting surface area necessary for the push button switch and the rotary switch is reduced.
Consequently, it is possible to provide a larger liquid crystal display panel on the upper surface of the camera body.
The push button switch contact member can be provided on a first switch portion of a main board (flexible printed circuit board), and the rotary switch contact member can be provided on a second switch portion which is formed by bending the main board to extend in a space defined between the push button switch contact member and the rotation operating portion.
Preferably, the shaft portion of the push button switch extends through a hole formed in the second switch portion, so that a lower end of the shaft portion abuts against the push button switch contact member.
The rotary switch contact member can include a conductive code plate formed on the second switch portion around the shaft portion, and a brush which is mounted to the rotation operating portion to come into sliding contact with the conductive code plate
