  • Patent number: 11231041
    Abstract: Various fan blade locking devices which operate to lock the blades of a fan in place and disconnect power to the fan. The locking device has an actuable bolt that, when in the locked position, extends to and contacts the fan blades and thereby stops the fan blades from turning. Additionally, the bolt has a contact washer coupled thereto such that the contact washer can engage with and disengage from a switch, thereby completing or interrupting a circuit supplying power to the fan, which allows for the locking device to prevent the fan from being actuated while the bolt is in contact with the fan blades.

  • Patent number: 8026784
    Abstract: This current invention is about a switching implement enabled to perform the remote-controlled switching of electric consumers, consisting of multiple electro-mechanical bistable switches, plus at least one actuating element allocated to the bistable switches such that it can selectively change the state of any of the bistable switches from one of its two states to the other and vice versa.

  • Patent number: 4392050
    Abstract: A rapid response thermal switch for isolated load control includes a bimetallic switch electrically connected to a controller and operatively connected to a switch follower which controls the operation of a second switch electrically connected to a load so that the load is electrically isolated from the controller. While energization of the bimetallic switch by the controller causes the bimetallic switch to move away from its switch follower, the switch follower is biased to follow the bimetallic switch. The initial movement of the switch follower allows the load current controlling switch to close, energizing the load. The bimetallic element, heated by the controller currents flexes to cycle itself on and off while maintaining the load controlling switch in the closed position. When the bimetallic element sufficiently cools after deenergization, it returns the bimetallic switch to its closed position.
