One end of its tubular handle defines a receptable receiving a spacer block to which is slip-fit a lamp socket and switch device received and frictionally clamped in their required position as a diametral split in the outer end portion of the receptacle wall structure accommodates laterally projected portions of the included switch.
A sleeve-like insert applied in receptacle and portion of the handle forms substantially dead air space within its interior wall surface which insulates the body of the inserted lamp socket.
