Abstract

Embodiments provide an electrical contact assembly (100). The electrical contact assembly includes a crossbar (102), a pivot pin (104) mounted in the crossbar, a contact arm (106) pivotally mounted on the pivot pin and rotatable about a pivot axis (107), a moveable electrical contact (108M) spaced from the pivot axis in a first arm portion (106A) of the contact arm, and a spring assembly (110) coupled between the crossbar and the contact arm, the spring assembly including a clevis pin (112A) and a spring (114) received on the clevis pin wherein an end of the clevis pin extends through the spring and is received in a pivot recess (126) in the crossbar. Electrical contact assemblies with offset rod ends and limit stops are also disclosed. Systems including the electrical contact assembly and methods of operating the electrical contact assembly are provided, as are other aspects.
