Detailed Description
The present invention will be described in detail with reference to the following embodiments. The following examples will assist those skilled in the art in further understanding the present invention, but are not intended to limit the invention in any way. It should be noted that various changes and modifications can be made by one skilled in the art without departing from the spirit of the invention. These all belong to the protection scope of the present invention.
As shown in fig. 1, the utility model provides a pair of reed switch position sensor, include: a reed circuit and a magnet; the magnetic reed circuit comprises a magnetic reed switch (REED SWITCH), and a magnet is arranged on the object to be detected; the object to be tested comprises at least two different position states, the object to be tested is close to the magnetic reed switch in the first position state, the magnetic reed switch is attracted, the object to be tested is far away from the magnetic reed switch in the second position state, and the magnetic reed switch is disconnected.
In order to avoid the electrostatic influence, the reed circuit further includes: an electrostatic protection device; the electrostatic protection device is connected in parallel with the reed switch. The electrostatic protection device may be two diodes connected in series in reverse, the cathodes of the two diodes being connected to each other. The magnet includes a magnet.
As shown in fig. 2, when the magnet is pressed down from the position 1 to the position 2, the distance between the magnet and the reed switch is reduced, and the reed switch is attracted; when the magnet rises from position 1 to position 2, the distance between the magnet and the reed switch increases and the reed switch turns off.
