  • Patent number: 6949713
    Abstract: A lighting system having a vibration switch for a footwear is disclosed. The system comprise a vibrating switch turning “on” or “off” responsive to motions of the footwear. The vibrating switch further comprises an isolating housing, a spring on the isolating housing, one end of the spring being a free end and another end thereof being a fixing end, a conductive plate in the isolating housing; a metal support plate in the isolating housing and being at another side of the conductive plate; and a first and a second pins; the first pin being connected to the conductive plate and extending out of the isolating housing; and the second pin connected to the metal support plate and extending out of the isolating housing. When the isolating housing vibrates, the free end of the spring will swing to contact the conductive plate so as to conduct current to the conductive plate.

  • Patent number: 5789716
    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.
