Abstract:
1. A switch, comprising: an insulative housing comprising two opposite side walls and a cavity formed between the side walls, each side wall defining a fixing groove; a plurality of fixed terminals fixed in the insulative housing, the fixed terminals comprising first, second and third fixed terminals respectively provided with a first contact portion, a pair of separated second contact portions and a pair of separated third contact portions exposed in the cavity; a movable contact residing in the cavity and comprising a deformable central contact portion; an electrical member having a pair of leads upholding the electrical member; a pair of elastic folded contacts respectively retainably disposed within the fixing grooves of the insulative housing, each elastic folded contact comprising one end supportably clamping the corresponding lead of the electrical member and another deflectable free end mechanically and electrically engaging with the corresponding second contact portion; an actuator moveably assembled to the insulative housing; and an operator positioned between the actuator and the movable contact; wherein when the operator is not downwardly pushed, the movable contact bridges the pair of third contact portions of the third fixed terminal while disconnects the first contact portion of the first fixed terminal; and wherein when the operator is downwardly pushed by the actuator to thereby depress the movable contact, said central contact portion is downwardly depressed by the operator to further contact the first contact portion of the first fixed terminal so as to establish an electrical connection between the first and the third fixed terminals.
