The present disclosure relates to a supplementary isolating device (1) for remote operation of a circuit breaker with interlocking functionality. The supplementary isolating device (1) comprises: an electrical disconnection switch (5) manoeuvrable between a mechanically lockable first position and a mechanically lockable second position, which electrical disconnection (5) switch is configured to be connected in the control circuit of a circuit breaker for an electrical drive system, wherein the supplementary isolating device (1) is configured to send a first control voltage to the circuit breaker to provide an electrical disconnect and interlocking the operation of the circuit breaker, when the electrical disconnection switch (5) is in the first position, an electric terminal (9) configured to be connected to an auxiliary contact of the circuit breaker to obtain an operational status of the circuit breaker, and an indicator (11) configured to indicate the operational status of the circuit breaker.

Disclosed are a communication module and a corresponding portable terminal, wherein the communication module comprises: an NGFF interface; a switch unit, used for controlling the connection and disconnection of the power supply of a power supply end of the communication module and a power source pin of the NGFF interface; a charging protection unit, used for charging when the switch unit turns off, and also used for eliminating an impulse current at the moment when the switch unit turns on; and a time delay unit, used for controlling that the switch unit turns on with a time delay. The present invention can guarantee the integrity and stability of data.

A switch includes: a hermetic vessel filled with an insulating medium; an insulating spacer dividing the hermetic vessel into heretic spaces; an electrode fixedly penetrating through the insulating spacer; and a plurality of circuit breaker parts inserted between conductors and the electrode in the hermetic spaces and serially connecting the conductors in a closed state, and having contacts including the electrode and operation parts driving the contacts. At least one and another circuit breaker parts are a vacuum circuit breaker part having the contact housed in a vacuum vessel and a circuit breaker part having the contact larger in dielectric strength than in the vacuum circuit breaker part. In an interrupting operation from the closed state, the contacts of the circuit breaker parts are opened, and the contact of the vacuum circuit breaker part is closed when or after the contact of the other circuit breaker part is opened.

This invention provides a highly reliable switch for maintaining a power supply ON state until data processing in a device is completed even if an operating element is manually ON operated to operate the device to be used and then the operating element is manually OFF operated with the stopping of the operation, and automatically turning OFF the power supply after the data processing is completed, and an electronic device. A switch is provided in which a rotation operating body (130) that does not receive an operation force from an operating element (120) when OFF operated is arranged inside the operating element (120), the rotation operating body (130) including a switch operating portion (132, 133) for turning ON a power supply switch mechanism (140) and a return spring regulating piece (134) for biasing a return spring (160) in an anti-biasing direction, where a regulating state of the return spring (160) regulated by the return spring regulating piece (134) is held, the ON state of the power supply switch mechanism (140) is held With a permanent magnet (173), and the ON state of the power supply switch mechanism (140) is released by applying a release force on the permanent magnet (173) when the power supply is reset.

This invention provides a switch in which the switch components are separately arranged at the portion where the switch components tend to be arranged in a concentrated manner in the housing without being collectively arranged in one region in the housing to achieve miniaturization and slimming, and in which the welding avoiding performance at the contact is enhanced to extend the lifespan, and an electronic device. A switch includes an operating clement (120) which is supported in a housing (110) and which is oscillation operated to one side and the other side, a power supply switch mechanism (180) for bringing contacts (186, 187) of a movable piece (182) and a fixed terminal (183) facing each other in the housing into contact with each other to turn ON a power supply in cooperation with the ON operation when the operating element (120) is oscillated to one side and ON operated, and a power supply reset mechanism (170) for holding and releasing the ON state of the power supply switch mechanism (180), wherein the power supply reset mechanism (170) is arranged on one side in an oscillation operating direction of the operating element (120), and the power supply switch mechanism (180) is arranged on the other side in the oscillation operating direction of the operating element (120).
