Abstract
An exemplary movable contact for an electric switch having a first contact blade and a second contact blade. Each of the first contact blade and the second contact blade includes an assembly hole. The movable contact having an assembly pin wherein the assembly pin includes a separation portion having a diameter greater than the assembly holes of the first and second contact blades thereby keeping the first and second contact blades separated from each other. The assembly pin includes a contact blade portion on each side of the separation portion for insertion to the assembly holes of the contact blades.
Claims15
A movable contact for an electric switch, comprising:
- a first contact blade;
- a second contact blade, wherein each of the first contact blade and the second contact blade includes an assembly hole;
- an assembly pin that includes a separation portion having a diameter greater than the assembly holes of the first and second contact blades thereby keeping the first and second contact blades separated from each other, the assembly pin having a contact blade portion on each side of the separation portion for insertion to the assembly holes of the contact blade;
- and
- a spring element connectable to the assembly pin for pressing the contact blades against ends of the separation portion of the assembly pin.
A method of mounting a movable contact, comprising:
- inserting a first contact blade portion of an assembly pin to an assembly hole of a first contact blade;
- inserting a second contact blade portion of the assembly pin to an assembly hole of a second contact blade, whereby the contact blades remain at a distance defined by a separation portion of the contact pin, which separation portion is located in the assembly pin between the two contact blade portions;
- and
- connecting a spring element to the assembly pin for pressing the contact blades against the ends of the separation portion of the assembly pin.
