Abstract: A switch includes an insulative housing, a fixed contact, a movable contact and an actuator. The insulative housing defining a receiving cavity enclosed by a number of peripheral walls each of which includes an inner surface exposed to the receiving cavity. The actuator includes a bottom portion slidably received in the receiving cavity, a bottom operator for deforming of the moveable contact and a button. The bottom portion includes a first side wall and a first rib protruding sidewardly therefrom. The first rib is slidable against a first inner surface of the peripheral walls while the first side wall is separated a distance from the first inner surface. As a result, contacting areas of the actuator and corresponding inner surface are greatly reduced, and soldering materials, such as flux, originally influencing movement of the actuator can be avoided.

Abstract: A switch includes an insulative housing, a pair of first and second contacts fixed in the insulative housing and a dome-shaped moveable contact. The insulative housing includes a receiving space and a first peripheral wall located outside of the receiving space. The first and the second contacts include first and second contacting sections, respectively. The first and the second contacting sections are separated a distance from each other and exposed in the receiving space. The dome-shaped moveable contact is mounted in the receiving space under condition that the moveable contact is constantly in contact with the second contacting section while the moveable contact is alternatively driven to engage with the first contacting section so as to establish electrical connection between the first contact and the second contact. The first peripheral wall defines a sinuated air-passageway communicating the receiving space to outside.

Abstract: A tilt switch (100) includes an insulative housing (2), a number of contacts (3) retained in the insulative housing, a conductive rotary ball (4), and a top cover (5) attached to the insulative housing. The insulative housing includes a bottom wall (21) and a number of vertical walls (22) cooperatively defining a receiving space (20). The bottom wall defines a plurality of passageways (211) and a plurality of cutouts (212). The cutouts extend along an up-and-down direction and communicates between the passageways and exterior. Each cutout has a smaller top end and a larger bottom end for preventing soldering material from entering into the receiving space. The contacts are retained in the passageways of the insulative housing. The rotary ball is received in the receiving space and connects with selected ones for establishing different states.

Abstract: A push-push switch includes a housing having a space, a plurality of stationary terminals received in the housing, a button assembled to the housing, a movable terminal assembled to the button, and a spring member located between the housing and the button. The space has a first post defining a protrusion thereon. The stationary terminal defines a contacting portion extending onto a surface of the first post and a soldering portion extending out of the housing. The movable terminal further defines a downwardly-extending contact arm and a downwardly-extending felt-generated spring arm extending from a planar base portion thereof while at different positions. The contact arm is established electrically connection with the contacting portion of the stationary terminal when the button is depressed, and the felt-generated spring arm is engaged with the protrusion of the first post in the meantime.

Abstract: A card connector, comprising: an insulative housing having a base, first and second sidewalls extending upwardly from two opposite sides of the base, a card receiving space defined by the base and the first and second sidewalls; a plurality of contacts held within the housing, the contacts having contact sections extending beyond the base; a pair of detecting switches including a stable switch and a movable switch both around a region located backwardly of the first sidewall; and a flange-like plane portion on said first sidewall and essentially vertical to said first sidewall, a front guiding entrance defined by said flange-like plane portion, the first sidewall, the second sidewall and the base.

The space has a first post defining a protrusion thereon. The stationary terminal defines a contacting portion extending onto a surface of the first post and a soldering portion extending out of the housing. The button defines a second post extending into the first post when the push-push switch is completely assembled. The movable terminal defines a base portion having a mounting hole around the second post for assembling the movable terminal on the button. The movable terminal further defines a downwardly-extending contact arm and a downwardly-extending felt-generated spring arm.
