The invention discloses a trigger of a tool switch and a production technique of the trigger. The trigger is prepared from, by weight, 20-35 parts of zinc borate, 0.5-4 parts of nano lanthanum oxide, 2-15 parts of magnesium oxide, 0.5-4 parts of nano cerium oxide, 1-5 parts of graphite fibers, 5-15 parts of chromium, 3-8 parts of nickel powder, 5-10 parts of attapulgite, 8-13 parts of manganese, 15-35 parts of aluminum powder, 20-40 parts of iron oxide and 1200-1600 parts of iron powder. The production technique of the trigger comprises the steps that when the temperature of a blast furnace reaches 200-350 DEG C, the raw materials are added, and a fluxing agent is added into the blast furnace at the same time; when the temperature of the blast furnace reaches 700-800 DEG C, a refining agent is added; when the temperature of the blast furnace reaches 700-800 DEG C again, a modificator is added for modification; and when the temperature of the blast furnace reaches 720-770 DEG C, slagging-off and discharging out of the furnace are conducted, and pouring is conducted rapidly, so that the trigger is obtained. The production technique is simple and environmentally friendly; the machined trigger has good performance in the aspects of tensile strength, bending strength, percentage elongation after fracture and the like, and market requirements are met completely.
