Abstract
A multi-position trigger switch on-board hand-held laser scanning heads controls aiming and reading of a symbol in separate operational states, all without using discrete aiming light subsystems. A head is aimable at the symbol during a first operational state wherein a static or dynamic aiming is illuminated on the symbol. During a second operational state, a dynamic reading zone extends across the symbol to read the same. The same laser beam is employed to illuminate both zones.
