Abstract

A flash switching arrangement for a camera which includes a shutter with an opening leaf and a closing leaf and has a contact nipple and a contact shoe for the attachment of flash units. The switching arrangement includes first and second switching means electrically connected between the first contact shoe and the contact nipple respectively. First coupling means are connectible between the first and second switching means and the opening leaf of the shutter. Second coupling means are connectible between the first and second switching means and the closing leaf of the shutter. On actuation of the shutter, the opening leaf effects closure of both the first and second switching means to ignite the flash unit and after exposure, the closing leaf effects opening of both the first and second switching means.
