Switches or switchgears with or without time-delays are known.
The invention can be used in low-voltage switchgear, in particular contactors.
The invention relates to a multiple break contact device for electrical switchgear.
The aim of the invention is to devise an interlocking device (1) for switchgear which interlocking device allows a plurality of switching devices to be interlocked in a simple manner.
The invention relates to an arrangement used to fix conductor rails for multi-phase switchgears.
Telephonic or telegraphic switching apparatus
Switching devices may have means for contactlessly detecting their position.
Telephonic or telegraphic switching apparatus (excluding relays and switching equipment such as selectors for automatic telephone exchangers
Telephonic or telegraphic switching apparatus (excluding relays and switching equipment such as selectors for automatic telephone exchangers
Switch gear for transmission and distribution of electricity
The invention relates to a connection system for devices (19), in particular safety switching devices.
Telephonic or telegraphic switching apparatus
The switching devices are preferably disposed on the substrate.
Such a switching device (1, 2, 3) therefore has a longer service life than conventional switching devices.
Switching devices of this type are used in low-voltage circuit-breaker arrangements.
This disclosure provides systems, methods, and apparatus for antenna switching.
This type of electric connection device is used in medium-voltage switching units.
The invention relates to an electrical connecting device for connecting separable connecting lines between at least two switch rooms, notably for medium-voltage switching units.
The present disclosure discloses methods and apparatuses of switching applications and adding entry information.
Switching devices often have a protective function, e.g. relative to a power supply system, thus making it desirable for defects and wear within the switching device to be recognized to support the protective function.
