Zusammenfassung:	An electronic flash unit includes a housing having an elongate passage. An electrical plug having a pair of contacts electrically connected to the flashtube-firing circuitry is movably mounted in the passage to locate the contacts at varying positions relative to the housing. The flash unit further includes a camera mounting bracket that is adjustable relative to the base of the housing. A ratchet mechanism prevents a control button operatively associated with the bracket and an electrical control switch from closing the switch to energize the flashtube-firing circuitry when the bracket engages the housing base.
