Abstract:
1. An electric torch comprising: a main body accommodating battery pack therein; a head assembly; and a rear assembly releasably engaged with a rear end of the main body; wherein the rear assembly comprises a rear cover for enclosing an electrically conductive spring, an electrically conductive cathode plate, and a magnetic controlled member therein, and seals the rear end of the main body; the spring is electrically engaged between negative terminal of the battery pack and the cathode plate; the magnetic controlled member, which is disposed between the cathode plate and rear end of the rear cover, can divert electric current flows in the torch under an attractive force of a magnet; the main body is electrically conductive, and given an electrically nonconductive surface treatment except for certain areas for electrically connection; the rear cover comprises a barrel and a tail block; the rear assembly further comprises a nonconductive ring; the spring, the cathode plate, the magnetic controlled member, the ring and the tail block are respectively co-axially assembled together and accommodated in the barrel with the tail block partially projecting rearward from rear end of the barrel; the ring is inserted between the cathode plate and the tail block, which defines a passage for receiving the magnetic controlled member therein; the barrel and tail block are electrically conductive, and the barrel is given an electrically nonconductive surface treatment except for certain areas for electrically connection.
