摘要： A three-stage control mechanism of an explosion-proof switch has a rotating unit and an interconnecting unit. The rotating unit has a first drive portion and a second drive portion that are selectively operated and reciprocated. The interconnecting unit includes a retaining seat and a connecting member. A switch unit is connected to the connecting member. An intermediate sleeve is insertedly connected to the connecting member and extends into the retaining seat. An outer sleeve is tightly sleeved on an outer wall of the intermediate sleeve. The outer sleeve is in tight fit with the retaining seat. A movable cover is provided between the outer sleeve and the rotating unit. A connecting rod assembly includes a first connecting rod and a second connecting rod that are inserted in the intermediate sleeve. The first and second connecting rods are respectively driven by the first and second drive portions.

摘要： Solid state and hybrid circuit protection devices include improved chemical, static discharge and impact resistant housing construction, arc-free switching operation, secure terminal assemblies and thermal management features. The solid state and hybrid circuit protection devices are ignition protected and avoid possible explosions and therefore obviate a need for conventional explosion-proof enclosures to ensure safe operation of an electrical power system in a potentially explosive environment.

摘要： This disclosure relates to ingress-tolerant input devices. Aspects of the disclosure relate to an ingress-tolerant switch assembly for operating an electronic device in an ingress-protected manner. The switch assembly includes a button configured to be coupled to an outer surface of an enclosure of the electronic device. The switch assembly also includes a spring operably coupled to the button and a magnet coupled to the spring. A pressing force applied by a user to the button overcomes a spring force of the spring to move the magnet into proximity of the magnetic sensor to cause the magnetic sensor to generate a sensor signal for performing a function of the electronic device.

摘要： An underwater device may include a waterproof housing defining a dry cavity and having a nonferrous switch interface wall. The underwater device may include a rotary switch within the dry cavity and including a switch body, and a switch shaft extending outwardly from the switch body. The underwater device may include a first magnetic body within the dry cavity and coupled between the switch shaft and the nonferrous switch interface wall, and a second magnetic body external from the waterproof housing and adjacent the nonferrous switch interface wall in alignment with the first magnetic body so that rotation of the second magnetic body rotates the switch shaft. Each of the first magnetic body and the second magnetic body may include a permanent magnet.

摘要： An electrical device such as, for example, an electrical switch is disclosed. The switch being arranged and configured to prevent ingress or intrusion of water, dust, or the like from the external environment thus making the switch particularly suitable for use outdoors or indoors where water and dust are expected. In one embodiment, the switch includes a base or housing, an internal actuator positioned within an internal cavity of the base, an external actuator accessible by a user, a barrier layer positioned between the internal actuator and the external actuator, the barrier layer arranged and configured to seal the internal cavity and the internal actuator, and a magnetic coupling arranged and configured to transfer movement of the external actuator to the internal actuator through the barrier layer.

摘要： A switch (30) for a hand-held power tool (10) or as a component of a hand-held power tool (10), which has an electric drive motor (16) that can be switched by the switch (30). The switch (30) has a switch housing (33) with a switch chamber (35) in which a switch actuator (75) that can be moved between at least two switch positions (ML, MR) is arranged in order to actuate an electric switch element, said switch actuator being kinetically coupled, by means of a transmission element (70), to a switch (30) actuation element (32), which is arranged outside the switch housing (33) and can be moved between at least two actuation positions (R, L), wherein the transmission element (70) passes through a through-opening (54) on a wall of the switch housing (33) such that the switch actuator (75) can be moved by moving the actuation element (32) in order to actuate the switch element (24). A rotary bearing (77) is arranged in the through-opening (54), the transmission element (70) being rotatably mounted on the rotary bearing about a rotational axis (D).
