Description
Technical field
The present invention relates to potentiometer technical field, espespecially a kind of accurate hollow potentiometer of long-life switching regulator.
Background technology
Switch and potentiometer belong to circuit regulation device together, in many cases, and switch and potentiometer matched together are such as opened
Potentiometer, or potentiometer with switch are closed, switch and two kinds of functions of potentiometer are provided simultaneously with.But, the switch current potential used at present
Device, or potentiometer with switch have the following disadvantages：
First, in the prior art, such as revolving type potentiometer, although switch and potentiometer matched together, but in structure
Switch and potentiometer are the two large divisions of complete parttion, and only rotating shaft is shared.Potentiometer include contact brush, carbon film circuit and
Copper foil circuit（Or it is silver-plated on copper foil）And rotor, contact brush is installed, contact brush rotates to realize in carbon film with rotor on rotor
It is upper to slide, so as to constantly change the contact position with carbon film, realize change in resistance.Switch includes switch movable contact piece（Switch contact
Brush）, switch stationary contact piece, switch movable contact piece is with axis of rotation, and realization is contacted with static contact（Switch connection）And separation（Switch is disconnected
Open）.It can be seen that, potentiometer and switch have respective contact brush and circuit.Cause complicated, parts increase, manufacturing cost
It is high.
Second, the trend that existing potentiometer resistance distribution is successively decreased in overall incremental or contact brush, it is impossible to realize that contact brush exists
Realize and be switched on or switched off halfway after turning an angle, and realize the resistance of output fixed range.
Third, existing potentiometer and switch are using upper separated exclusive use, it is impossible on identical product（Refer to potentiometer and
Switch is assembled into identical product, such as potentiometer with switch）Association is used.So-called association is mutually interted using referring to using upper associated,
Being respectively and independently separated for prior art can be avoided to use.
The content of the invention
