Patent ID: 7564003

Claim:
A detect switch, comprising: an insulative housing defining a cavity therein; a plurality of fixed terminals embedded in the insulative housing, the fixed terminals comprising a first, a fourth and a selected fixed terminals respectively provided with a first contact portion, a fourth contact portion and a selected contact portion exposed in the cavity; a moveable contact formed with at least a pair of periphery contact portions in contact with the fourth contact portion and the selected contact portion to electrically connect the fourth and the selected fixed terminals, each periphery contact portion formed with a protrusion, one of the protrusions resisting against the selected fixed terminal; and a driving mechanism moveably assembled to the insulative housing; wherein when the moveable contact is downwardly depressed by the driving mechanism to have a central contact portion thereof contact with the first contact portion of the first fixed terminal, the periphery contact portions of the moveable contact are urged to tilt upwardly due to a support movement of the protrusions for leaving away from corresponding fixed terminals to thereby insulate the selected fixed terminal and the fourth fixed terminal and electrically connect the first fixed terminal and the selected fixed terminal due to an engagement between the first contact portion and the central contact portion and a resisting movement of corresponding protrusion against the selected fixed terminal.
