The main shell has a front shroud portion (311) surrounding the tongue portion of the insulative housing and a rear portion (312) supporting the base portion. The front shroud portion forms at least one embossed portion (313) thereon. The sub shell is attached to the rear portion of the main shell and has a curve portion (321) abutting against a rear end of the front shroud portion to enclose the base portion of the insulative housing. The main shell and the sub shell each have curve arms (3102, 3202) abutting against the rear ends of the locking pieces.

Abstract: An elastic sheet (5) comprises a first sheet (10) plated a metal film (11) on an upper surface thereof, a number of moveable contacts (20) attached on a lower surface of the first sheet (10), a second sheet (30) affixed on the lower surface of the first sheet (10) and defining a number of receptacle holes (31) corresponding to the moveable contacts (20). The second sheet (30) extends curved an extending portion (5) from a lateral side thereof and defines a recess (5) in the extending portion (5) thereof. A switch comprises the elastic sheet (5) and a circuit board (6). When the moveable contacts (20) engage with the fixed contacts, the elastic sheet (5) is affixed on the circuit board (6) by the adhesive on the second sheet (5), and then the first extending portion (5) connects to the circuit board (6) for contacting a ground end thereof.

Abstract: An electrical connector comprising an insulative housing having a base potion and a tongue portion extending therefrom; a plurality of contacts arranged in the insulating housing; and a metal shell receiving the insulative housing therein, comprising a main shell and a sub shell attached to the main shell; the main shell having a front shroud portion surrounding the tongue portion of the insulative housing, wherein at least one embossed portion extending from the front shroud portion, and a rear portion supporting the base portion; the sub shell attached to the rear portion of the main shell and having a curve portion abutting against the front end of the front shroud portion to enclose the base portion of the insulative housing.

Abstract: A detect switch (100) includes an insulative housing (1), a first and second fixed terminals (51, 52) retained in the insulative housing, a moveable contact (3), an operator assembly (2) and a cover (4) mounted on the insulative housing. The operator assembly (2) comprises a rotator (22) lying over the moveable contact, and an actuator (21) cooperating with the rotator (22) to drive the moveable contact. The moveable contact is formed with a pair of contacting portions (311, 321), a width of which is smaller than that of the fixed terminals. The contacting portions come to contact with and thereby electrically connect the fixed terminals when the operator assembly is manipulated.

Abstract: A movable contact body includes a separator (13), a number of domes (12), an insulative film (11) and a shielding (10). The separator is made of insulative material and is substantially a planar sheet. The domes are made of resilient conductive material and are located on the separator in pre-determined locations. The insulative film coats on upper surfaces of the domes. The planar shielding is made of conductive material and coats on the insulative film. The planar shielding defines a number of openings (100) in predetermined locations corresponding to the domes. Each opening receives one dome therein.

Abstract: A dome sheet for a panel switch includes a planar and resilient metal sheet (1), a number of domes (2) punched from the metal sheet, and a number of positioning members (3) made of insulative material for positioning the domes with the metal sheet. A manufacturing process for the dome sheet includes steps of processing a metal sheet to form a number of original domes (22) partially separate from the metal sheet, applying a plurality of positioning members to fix the original dome to the metal sheet, and electrically isolating the original dome from the metal sheet.

Abstract: A combined control electrical switch (1) includes an insulative housing (2), an actuator (3), a movable contact (4), a torsion spring (5), and a cover (6). The housing has a base (20) and a C-shaped periphery wall (27) defining a pair of slits extending upwardly, thereby defining a cavity (201) therein. A plurality of fixed contacts (23, 24, 25) are mounted in the housing for detecting a rotating operation or depressing operation of the actuator. The actuator mounted on the housing is rotatable and depressable. The movable contact is attached to the actuator, so that the actuator is movable on the housing and then return to its original position. The torsion spring is mounted between the actuator and the housing and comprises a pair of arms (52) and bent ends (53).
