ABSTRACT:
A writing instrument with a light assembly includes an elongated insulating switch bar, an insulating sleeve member, a pair of conductive tongues and a metallic clip assembly. The switch bar has two split members which extend radially and downwardly to define a receiving slot therebetween. The insulating sleeve member is sleeved around the split members and has two radial holding ribs which extend into the engaging slot of the switch bar and which is provided with a respective elongated engaging groove. Each of the conductive tongues has a section press-fitted into the engaging groove of the respective holding rib of the sleeve member to mount the former on the latter. The conductive tongues have two curved portions that cooperate to form a clamping ring between the split members. A conductive locking bolt extends axially into the receiving slot and engages the clamping ring and is fastened simultaneously to the switch bar to retain the sleeve member on the switch bar.
