  • Publication number: 20210036637
    Abstract: An electrical switch unit for use with a variable speed electrical device includes a housing for a pair of electrical switching contacts, and an actuator operably connected with one of those contacts. A signaling module is associated with the electrical switch unit, and has signaling circuitry for sensing the movement of the actuator and outputting a signaling module signal indicative of the sensed movement or position of the actuator. A power module with a power switching device controllably supplies power from the DC power source to the DC motor at a speed corresponding to the sensed movement or position of the actuator. A control module receives the signaling module signal, and outputs a control module signal to control the power module.

  • Publication number: 20200393630
    Abstract: A fiber optic connector deploys a latch lever release with an elastic rib. When the latch lever release is depressed down or toward the optical axis of the connector, a hook seated within a recess of the connector outer housing, the hook is lifted out of the recess thereby allowing the connector to be removed from the adapter port. A pivot point is formed between the main body of the latch lever release and the connector outer housing. Depressing the latch lever release distal of the pivot point at the trigger portion displaces the hook from the connector thereby allowing the user to remove the connector from a receptacle port, such as an adapter port.
