Abstract
A rear pushbutton type switch arrangement for flashlight formed of an aluminum alloy barrel holding a battery set and a lamp assembly, an electrically conducting rotary rear cap provided at a rear side of said barrel and a switch structure is disclosed. The switch structure has an externally threaded, electrically conducting, hollow, cylindrical metal casing connected between the barrel and the rotary cap to hold the other parts of the switch structure firmly in the rotary rear cap so that the other parts of the switch structure do not fall from the rotary rear cap when disconnected from the barrel for a replacement of the battery set.
