    摘要： A double-throw contact assembly, particularly for relay switches, or push button switches of the non-locking type, having a break contact, a make contact, and a pair of flexible contact arms associated therewith. Each contact arm is fixed adjacent one of its ends at a clamp point and has a free end movable into and out of contact with one of the break and make contacts. In their relaxed state, the arms converge at the clamp point from a bend intermediate the free end and the clamp point, thereby to define two linear portions or segments for each arm, a first straight segment for each arm extending from the clamp point to the bend, and a second straight segment for each arm extending from the bend to the free end of the arm.
