Dial switch is a relatively common type of switch, in use we also want to do a good job of understanding the common problems in general, which does not work the reason we also want to understand in general, the following we will talk about the dial switch does not work what are the reasons?

1. magnet supplier supply magnet whether there is a period of time after some of the magnet demagnetization, resulting in part of the Hall induction.

Also pay attention to the Hall components and magnets between the spacer (spacer will also demagnetize).

2. Whether the pull-up resistor connected to the Hall switch is damaged, resulting in a small resistance value.

3. Whether the temperature of the working environment exceeds the rated value of the Hall element, high temperature may lead to damage of the Hall switch chip, and may also lead to demagnetization of the magnet.

4. Voltage, current is stable for a long time (can make the Hall bad Z big reason), whether in the operating voltage range
