Abstract

A moving contact assembly (26) for a civil range electric equipment circuit breaker has a simple lightweight construction and comprises a contact holding body (31), at least one moving contact (19,23), and means (32) of attachment for spring mounting said moving contact (19,23) on the contact holding body (31), which means comprise a pin (48) jutting out of the contact holding body (31) and engaging in a hole (49) formed in the moving contact (19,23), a forked spring (51) having prongs (53,54) wound into a spiral around the pin (48) on opposed sides of the moving contact (19,23), the base (52) of the forked spring (51) constantly biasing the moving contact (19,23) toward the fixed contact, and the ends (55, 56) of the prongs (53,54) engaging against the contact holding body (31), and retainer means (60) for retaining the moving contacts (19,23) axially on the pin (48).
