Abstract
A flash output control apparatus for a camera comprises a switch including a contact segment movable between a first electrical contact and a second electrical contact, and control means. Interlocking with the full opening of exposure aperture by the shutter device, the contact segment moves apart from the first contact and then comes into contact with the second contact. When the contact segment leaves the first contact toward the second one, the flash output control circuit is brought into operation. Thereafter, when the contact segment comes into contact with the second contact, the flash tube starts flashing.
