Abstract
A sealed pushbutton switch (1) includes an insulative housing (2), a number of fixed contacts (7), an actuator (3) moveably retained in the insulative housing, a moveable contact (6) fastened to the actuator and including a pair of elastic beams (62) each provided with a contact portion (621) contactable to corresponding fixed contacts to establish a reliable electrical connection between the fixed contacts, and a spring (5) mounted below the actuator. When the actuator is pushed, the moveable contact has an agile movement to break the electrical connection between the moveable contact and the fixed contacts.
Claims17
A sealed pushbutton switch, comprising:
- an insulative housing defining a cavity;
- a plurality of fixed contacts;
- an actuator moveably retained in the cavity of the insulative housing;
- a moveable contact fastened to the actuator and comprising a plurality of elastic beams each provided with a contact portion contactable to corresponding fixed contacts;
- and
- a spring mounted below said actuator;
- wherein when said actuator is pressed and moves together with said moveable contact from a first position to a second position relative to the insulative housing along a top-to-bottom direction, an electrical connection between said moveable contact and the fixed contacts comes to break.
A sealed pushbutton switch, comprising:
- an insulative housing defining a cavity;
- a plurality of fixed contacts each defining a mounting leg extending in a first direction;
- an actuator moveably having a portion retained in the cavity of the insulative housing;
- a moveable contact mounted upon said portion of the actuator and comprising a plurality of elastic beams each provided with a contact portion contactable to corresponding fixed contacts;
- and
- a spring mounted behind said actuator;
- wherein
- when said actuator is pressed and moves together with said moveable contact from a first position to a second position relative to the insulative housing along second first direction perpendicular to the first direction, the contact portion an electrical connection between said moveable contact and the fixed contacts changes under a condition that the contact portion exerts forces upon the corresponding fixed contacts in a third direction perpendicular to both the first and second direction for not affecting the actuator and the mounting legs.
