Abstract
A hand-held torch (100) includes a housing (110). A fuel flow path (208) is defined within the housing (110). A plunger (216) is movable within the housing (110) to control fuel flow through the fuel flow path (208). An engagement portion (222) is coupled to the plunger (216). A latching mechanism (220) having at least one claw (304) is movable to engage the engagement portion (222) when the plunger (216) is positioned to allow fuel flow through the fuel flow path (208). An actuator (114) is coupled to the latching mechanism (220) and exposed for manipulation by a user to move the latching mechanism (220) into engagement with the engagement portion (222).
