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.
