Embodiment Construction
[0036] First, refer to figure 1 The structure and operation of the switching device 1 according to the invention are described, figure 1 A schematic sectional view of the switching device along its central axis M in the normal operating state N in the open position A is shown. The switching device 1 comprises a switching unit 2 and a safety unit 3 which act on a switching member 4 in the form of a contact bridge. The switching member 4 is configured such that it can be joined together in the switching direction T with the counter contact 5 .
[0037] The switching unit 2 is configured as a monostable relay or a contactor and comprises a coil 20a which is arranged concentrically around the center axis M and which together with a coil core 20b and a yoke 20c forms a switching drive 20 of the switching unit 2, Where the coil core 20b is displaceable parallel to the switching direction T and is also arranged concentrically with respect to the center axis M, the yoke 20c substant...

The present invention relates to a switching device (1) for opening and closing a load circuit, in particular in an electric vehicle, having at least one switch contact (4a) which can be moved from an open position (A) into a closed position (B) and which is held at a distance from a counter-contact (5) in the open position (A) and is in electrically conductive abutment with the counter-contact (5) in the closed position (B). The invention further relates to a method for switching a load circuit, in particular in an electric vehicle, at least one switch contact (4a) being moved from an open position (A) into a closed position (B) and thereby being brought into electrically conductive contact with a counter-contact (5). In order to provide the most compact, light, cost-effective and reliable switching and separation unit for load currents, it is provided according to the invention that, in a safety position (C), the at least one switch contact (4a) is held separated from the counter- contact (5) in order to protect the load circuit.
Description
technical field [0001] The invention relates to a switching device for opening and closing a load circuit, in particular an electric vehicle, said switching device having at least one switching contact which can be moved from an open position into a closed position and which The head is held at a distance from the opposing contact in the open position and is in conductive abutment with the opposing contact in the closed position. [0002] The invention also relates to a method for switching a load circuit, in particular in an electric vehicle, at least one switching contact being moved from an open position into a closed position and thereby making conductive contact with an opposing contact. Background technique [0003] Methods and switching devices of the above-mentioned type for switching load circuits are known in the prior art. They are used for repetitive switching, for example, to be able to disconnect the battery or accumulator of an electric vehicle from a consume...
