Abstract
An electrical switch includes a dielectric casing, first and second terminal units, and an actuating unit. The dielectric casing includes a cover and a, mounting seat. The mounting seat is disposed in and attached to the cover. each of front and rear ends of the mounting seat is formed with a notch. Each of the first and second terminal units extends into the cover through the notch in a respective one of the front and rear ends of the mounting seat. The actuating unit extends into and is coupled to the cover, and is operable so as to selectively connect and disconnect the first terminal unit to and from the second terminal unit.
Claims6
An electrical switch, comprising:
- a dielectric casing including a cover that includes opposite front and rear walls, which cooperatively define an accommodating space therebetween, and a mounting seat that is disposed in said accommodating space in said cover, said mounting seat including
- a base wall that has opposite front and rear ends, each of which is attached to a respective one of said front and rear walls of said cover and is formed with a plurality of notches, and
- a plurality of dividing walls that cooperatively define a plurality of lower slots, each of which is in spatial communication with a respective one of said notches in said front end of said base wall of said mounting seat and a respective one of said notches in said rear end of said base wall of said mounting seat;
- a first terminal unit including a plurality of conductive terminals, each of which extends into a respective one of said lower slots in said mounting seat through a respective one of said notches in said front end of said base wall of said mounting seat, each of said conductive terminals of said first terminal unit having
- a secured section that is provided with a pair of projections, each of which engages a respective one of an adjacent pair of said dividing walls of said mounting seat, and
- a curved section that extends from said secured section of a respective one of said conductive terminals of said first terminal unit and that is movable relative to said dielectric casing;
- a second terminal unit including
- a plurality of conductive terminals, each of which extends into a respective one of said lower slots in said mounting seat through a respective one of said notches in said rear end of said base wall of said mounting seat;
- an actuating unit including a plurality of actuators, each of which extends into said accommodating space and is coupled to said cover, each of said actuators being operable so as to selectively connect and disconnect said curved section of a respective one of said conductive terminals of said first terminal unit to and from a respective one of said conductive terminals of said second terminal unit;
- and
- a plurality of retaining units, each of which prevents movement of said secured section of a respective one of said conductive terminals of said first terminal unit away from said base wall of said mounting seat, each of which is disposed in a respective one of said lower slots in said mounting seat, and each of which includes a pair of protrusions that are respectively provided on an adjacent pair of said dividing walls of said mounting seat,
- wherein said secured section of each of said conductive terminals of said first terminal unit is disposed between said base wall of said mounting seat and a respective one of said retaining units.
