One-way shaking switch
First Claim
1. A one-way shaking switch comprising a housing, a steel ball, a spring, a cover board and an upper and a lower metal terminals, said shaking switch being characterized in that:
- an interior of the housing is integrally formed with a circular cavity, a transverse cavity and a longitudinal rectangular cavity disposed between the circular cavity and the transverse cavity, two steps being formed on two sides of the housing without extending into the transverse cavity, two pairs of posts being respectively symmetrically disposed on the steps;
the lower terminal is inserted and secured in the transverse cavity of the housing, the steel ball being placed in the circular cavity and the spring being disposed in the rectangular cavity, one end of the spring riding over a terminal leg of the lower terminal, the other end of the spring being disposed with a ring member bearing or retaining the steel ball; and
the upper terminal is placed on the steps of the housing over the lower terminal, the cover board being overlaid on the upper side of the housing to close an opening thereof in the top ends of the posts being punched flat to fixedly associate the cover board with the housing.

Abstract
A one-way shaking switch including a housing, a steel ball, a spring, a cover board and an upper and a lower metal terminals. The housing is integrally formed with a circular cavity, a transverse cavity and a longitudinal rectangular cavity disposed therebetween. Two steps are formed on two sides of the housing. Two pairs of posts are respectively symmetrically disposed on the steps. The lower terminal is fixedly inserted in the transverse cavity, the steel ball is placed in the circular cavity while the spring is disposed in the rectangular cavity. One end of the spring rides over a terminal leg of the lower terminal. The other end of the spring is disposed with a ring member depressing or retaining the steel ball. The upper terminal is placed on the steps of the housing over the lower terminal. The cover board is fixedly overlaid on the housing to secure the above elements in the housing. When the shaking switch is placed in a positive state, the weight and shaking force of the steel ball are loaded on the ring member of the spring, making the spring one-way swing to touch the upper terminal so as to electrically connect the upper terminal with the lower terminal. The resilience of the spring leads to continuous swinging of the spring, so as to intermittently contact with the upper terminal for achieving a flickering effect for a light emitting element.
