A biasing member located within the bore, the biasing member engaging the first end of the plunger, the biasing member allowing for the manual movement of the plunger without harm to the switch of the material dispenser during use. ## Claims ### Claim 1 A control assembly for a material dispenser comprising: a plunger movably located within a bore of the control assembly, the plunger having first and second ends, the first end having an abutment for moveably retaining the plunger within the bore and the second end for engaging a switch during operation of the material dispenser to cease operation; and a spring located within said bore, the spring engaging the first end of said plunger, the spring allowing for the manual movement of the plunger after electrical shutoff without harm to the switch of the material dispenser during use. ### Claim 2 (depends on 1) The control assembly of claim 1 wherein said switch comprises a limit switch that enables and disables a motor that drives a rod coupled to a piston, the piston dispensing material from the material dispenser during operation. ### Claim 3 (depends on 2) The control assembly of claim 2 wherein said plunger is eccentrically spaced from and extends parallel to said rod. ### Claim 4 (depends on 2) The control assembly of claim 2 wherein said rod resides within a secondary bore and said assembly further comprises an adjustment member controlling the amount of travel of said plunger during operation of said material dispenser. ### Claim 5 (depends on 2) The control assembly of claim 2 wherein said motor is coupled to said rod by a gear train. ### Claim 6 (depends on 5) The control assembly of claim 5 wherein said rod is a geared rack that engages a pinion in said gear train. ### Claim 7 (depends on 2) The control assembly of claim 2 wherein said rod and piston concentrically share a first axis and said plunger and bore concentrically share a second axis, said first axis being eccentrically spaced from said second axis. ### Claim 8 (depends on 7) The control assembly of claim 7 further comprising a handle wherein said handle is attached to said rod with a first adjustment member and said plunger is disposed within said bore by a second adjustment member. ### Claim 9 (depends on 2) The control assembly of claim 2 wherein said bore is disposed within an adjustable body, the adjustable body movable relative to said handle and fixedly positioned along said handle by an adjustment spacer. ### Claim 10 (depends on 9) The control assembly of claim 9 wherein said adjustable body is substantially non-concentrically located within said handle. ### Claim 11 (depends on 2) The control assembly of claim 2 wherein said rod further comprises a handle coupled to a first end of the rod opposite a second end of said rod, said bore being disposed within said handle, allowing the manual advancement of said handle, rod, and piston without harm to said switch. ### Claim 12 (depends on 11) The control assembly of claim 11 further comprising an adjustment member coupled to said rod and handle, the adjustment member controlling the amount of travel provided by said rod and piston. ### Claim 13 (depends on 12) The control assembly claim 12 wherein said handle is substantially non-concentrically located about said rod, said bore is substantially concentrically located about said plunger, and said handle is located about said adjustment member. ### Claim 14 (depends on 13) The control assembly of claim 13 further comprising a secondary bore in said handle for supporting said rod. ### Claim 15 A control assembly for a material dispenser comprising: a plunger movably located within a bore of the control assembly, the plunger having first and second ends, the first end having an abutment for moveably retaining the plunger within the bore and the second end for engaging a switch during operation of the material dispenser to cease operation, said switch comprises a limit switch that enables and disables a motor that drives a rod; a handle coupled to a first end of the rod opposite a second end of said rod, said bore being disposed within said handle, allowing the manual advancement of said handle, and rod without harm to said switch; and a spring located within said bore, the spring engaging the first end of said plunger, the spring allowing for the manual movement of the plunger after electrical shutoff without harm to the switch of the material dispenser during use. ### Claim 16 (depends on 15) The control assembly of claim 15, wherein said rod extends along a first axis and said plunger and bore concentrically share a second axis, said first axis being eccentrically spaced from said second axis. ### Claim 17 (depends on 15) The control assembly of claim 15, wherein said handle is substantially non-concentrically located about said rod. ### Claim 18 (depends on 15) The control assembly of claim 15, wherein said rod is coupled to a piston, the piston dispensing material from the material dispenser during operation. ### Claim 19 (depends on 18) The control assembly of claim 18, comprises an adjustment member coupled to said handle, the adjustment member controlling the amount of travel provided by said plunger within said bore. ### Claim 20 A control assembly for a material dispenser comprising: a plunger movably located within a bore of the control assembly, said bore is disposed within an adjustable body, the adjustable body movable along a handle and fixedly positioned along said handle by an adjustment spacer, the plunger having first and second ends, the first end having an abutment for moveably retaining the plunger within the bore and the second end for engaging a switch during operation of the material dispenser to cease operation, said switch comprises a limit switch that enables and disables a motor that drives the rod coupled to a piston wherein said adjustable body is substantially non-concentrically located within said handle; and a spring located within said bore, the spring engaging the first end of said plunger, the spring allowing for the manual movement of the plunger after electrical shutoff without harm to the switch of the material dispenser during use.
