Abstract
An electrical switch includes an insulative housing (10), a set of fixed contacts fastened in the housing, a movable contacts (30) received in the housing, a load plate (40) mounted above the movable contact, a spring (50) mounted in the load plate, a driver (60) defined on the load plate, a shell (70) surrounding the housing, a knob (80) assembled with the load plate, and a push button (90) assembled on the load plate. While rotating the knob, the load plate is accordingly rotated, and the movable contacts are driven to contact with some of the fixed contacts, which enables rotary operation. While pressing the push button, the driver is pressed to move downwardly to press the movable contacts for contacting with the fixed contacts, which enables pushing operation.
Claims18
An electrical switch comprising:
- an insulative housing having an opening;
- a set of fixed contacts embedded in the housing;
- a movable contacts received in the opening;
- a shell covering the opening;
- a load plate positioned in the opening for cooperating with the movable contact;
- a spring assembled with the load plate;
- a driver drilling through the load plate and abutting against the movable contact;
- and
- a knob;
- wherein
- while the driver is pressed, the movable contacts is elastically deformed for contacting with the fixed contacts, and while the knob is rotated, the load plate actuates the movable contact to contact with the fixed contacts.
An electrical switch comprising:
- an insulative housing having a receiving cavity therein;
- a set of fixed contacts disposed to the housing;
- a deflectable contacts moveable within said receiving cavity;
- a load plate engageable with and cooperating with the deflectable contact;
- a spring positioned about the load plate and constantly urging the load plate to be in an initial position relative to a rotation position;
- a first actuation device actuating the deflectable contact vertically so as to have the deflectable contact engage at least one of said fixed contacts;
- and
- a second actuation device actuating at least one of said load plate and said deflectable contact to rotate abut an axis which extends vertically so as to have the deflectable contact engage at least another one of said fixed contacts.
An electrical switch comprising:
- an insulative housing having a receiving cavity therein;
- a set of fixed contacts disposed to the housing;
- a deflectable contacts moveable within said receiving cavity;
- a load plate engageable with and cooperating with the deflectable contact;
- a first actuation device actuating the moveable contact vertically so as to have the deflectable contact engage at least one of said fixed contacts;
- and
- a second actuation device actuating at least one of said load plate and said deflectable contact to rotate abut an axis which extends vertically so as to have the deflectable contact engage at least another one of said fixed contacts;
- wherein
- said deflectable contact defines a central portion and a periphery under a condition that the central portion is up-and-down moveable relative to the periphery while the periphery is up-and-down curved along a circumference thereof.
