Abstract
The utility model is a normally closed dry reed tube magnetic-controlled switch, comprising a dry reed tube which consists of a reed and a tube shell, a fixed magnet, a substrate and a directing magnet, with the dry reed tube arranged on the substrate, in which one side direct lower part of two reed contacting points of the dry reed tube is embedded with a fixed magnetic and the directing magnetic action is arranged on the direct upper part of the other side, with the same polarity of the facing sides between the directing magnetic and the fixed magnetic. In normal times, the influence of the magnetic field of the fixed magnetic realizes the constant closed status, but when the directing magnetic comes close, the same polarity caused by the magnetizing of the contacting sides of the two reeds separates the reeds for rejection, thus realizing the operation by seperating. The utility model realizes the constant closed status and is convenient for use.
Description
Technical field
The present invention relates to switch, particularly to the improvement of dry-reed tube switch.
Background technology
Tongue tube has a wide range of applications in electronic circuit, household electrical appliance, automation field.It is the reed of being made by two ferromagnetic materials that are encapsulated in the shell, and is connected with reed and its pin of drawing from shell is formed.Under the action of a magnetic field, the mutual adhesive of reed, the break-make of realization circuit.Existing tongue tube is a closure when external magnetic field is arranged, and disconnects during no magnetic field, is open type, when circuit design needs normally closed switch, itself can't realize, can only cause the circuit complexity by the conversion of circuit, uses inconvenience.
Summary of the invention
The utility model purpose is to provide a kind of normally closed dry reed pipe switch, with convenient use at circuit.
Scheme of the present utility model is: the normally closed dry reed pipe magnetic switch, comprise tongue tube, fixed magnet, the substrate formed by reed and shell, and controlling magnet, tongue tube is installed on the substrate, in substrate, be embedded with fixed magnet under one side of two reed contact points of tongue tube, the controlling magnet activity be installed in opposite side directly over, the end polarity that controlling magnet is relative with fixed magnet is identical.
The utility model has the advantages that: when controlling magnet away from the time, under the action of a magnetic field of fixed magnet, the reed adhesive of tongue tube, realize normally off, when controlling magnet near the time because controlling magnet and fixed magnet are located at the both sides of tongue tube two reed contact points respectively, and a relative end polarity is identical, this moment two reeds contact jaw magnetization after polarity identical, mutually exclusive and separate the realization opening operation.The utility model has been realized the normally off of tongue tube, has made things convenient for use.
Description of drawings
The utility model is described in further detail with embodiment with reference to the accompanying drawings below.
Accompanying drawing is a structural representation of the present utility model.
1 tongue tube among the figure, 2 controlling magnets, 3 substrates, 4 fixed magnets.
Embodiment
Referring to accompanying drawing, the normally closed dry reed pipe magnetic switch of embodiment, comprise tongue tube 1, fixed magnet 4, the substrate 3 formed by reed and shell, and controlling magnet 2, tongue tube 1 is installed on the substrate 3, in substrate 3, is embedded with fixed magnet 4 under the side of two reed contact points of tongue tube 1, controlling magnet 2 activities be installed in opposite side directly over, the end polarity that controlling magnet 2 and fixed magnet 4 are relative is identical.
During work, when controlling magnet 2 away from, under the action of a magnetic field of fixed magnet 4, the reed adhesive of tongue tube 1 realizes normally off.
When controlling magnet 2 near the time, because controlling magnet 2 and fixed magnet 4 are located at the both sides of 1 two reed contact points of tongue tube respectively, and a relative end polarity is identical, the polarity after the contact jaw of two reeds magnetization at this moment is identical, mutually exclusive and separate, realize opening operation.
Claims (1)
