Thermostat construction having a one piece plunger with a wing-like section and method of making the same

In a method of making a thermostat construction having a frame means carrying a fixed contact and a movable contact carried by a switch blade, a bimetallic snap disc carried by said frame means for controlling movement of said switch blade relative to said fixed contact in response to temperature sensing conditions of said bimetallic snap disc, temperature setting means carried by said frame means for selecting the temperature of operation of said disc for moving said movable contact out of contact with said fixed contact, said blade having opening means passing therethrough, said temperature setting means comprising plunger means passing loosely through said opening means and engaging said snap disc, said temperature setting means having means operatively associated with said plunger means to urge said plunger means into engagement with said snap disc, said temperature setting means having adjusting means for adjusting the force of said spring means that urges said plunger means into said engagement, the improvement comprising the steps of forming said plunger means as a one-piece member, forming said plunger means with a wing-like section provided with opposed ends, forming one end of said wing-like section to be engageable with said blade on opposite sides of said opening means thereof, forming said one end of said wing-like section to have a post means extending substantially centrally therefrom and projecting through said opening means of said blade, and causing said spring means to have one end thereof bearing against said post means.
