Abstract
Electrical switch contact sets are disclosed. A disclosed example apparatus includes a movable platform having first and second contacts, where the first and second contacts electrically coupled via the movable platform, and a stationary portion having third and fourth contacts, where the movable platform is movable to bring the first and second contacts in contact with the third and fourth contacts, respectively, to simultaneously close a current path of an electrical circuit associated with the first, second, third and fourth contacts.
Claims20
An apparatus comprising:
- a plunger having a movable platform with first and second contacts, the first and second contacts electrically coupled via the movable platform, the plunger to move along a linear motion path;
- a stationary portion having third and fourth contacts, wherein the movable platform is movable to bring the first and second contacts in contact with the third and fourth contacts, respectively, to complete a current path of an electrical circuit associated with the first, second, third and fourth contacts;
- and
- fifth and sixth contacts of the movable platform to be brought into contact with seventh and eighth contacts, respectively, of the stationary portion when the first and second contacts are moved away from the third and fourth contacts due to movement of the plunger along the linear motion path.
An electrical switch comprising:
- first contacts mounted to a movable platform of a plunger that moves along a linear motion path, the first contacts electrically coupled via the movable platform;
- second contacts mounted to a stationary portion, wherein the movable platform is movable to bring the first contacts in contact with the second contacts, respectively, to define a current path of an electrical circuit;
- and
- third contacts of the movable platform to be brought into contact with fourth contacts, respectively, of the stationary portion when the first contacts are moved away from the second contacts due to movement of the plunger along the linear motion path.
A method comprising:
- coupling a movable platform of a plunger to an electrical switch, the plunger to move along a linear motion path, the movable platform having first and second contacts, the first and second contacts electrically coupled via the movable platform;
- aligning the first and second contacts to third and fourth contacts, respectively, of a stationary portion of the electrical switch so that the third and fourth contacts can be brought into contact with the first and second contacts, respectively, to define a current path of an electrical circuit associated with the first, second, third and fourth contacts when the movable platform is moved along the linear motion path;
- and
- aligning fifth and sixth contacts of the movable platform to seventh and eighth contacts, respectively, of the stationary portion such that when the first and second contacts are moved away from the third and fourth contacts due to movement of the plunger along the linear motion path, the fifth and sixth contacts are brought into contact with the seventh and eighth contacts, respectively.
