dustproof
Dust falling on the surface of the switch can cause electrostatic
adsorption and poor contact of the metal contacts. Although the
device itself has made certain measures in anti-static, when the
static electricity exceeds a certain intensity, it will still cause fatal
damage to the electronic components on the internal circuit board.
To avoid the static electricity affecting the normal operation of the
device, please pay attention to the following:
1、Regular dust removal to keep indoor air clean;
2、Make sure that the equipment is well grounded to ensure
the smooth transfer of static electricity.
interference
Electromagnetic interference will affect the electronic components
such as capacitors and inductors inside the device by means of
capacitive coupling, inductive coupling, impedance coupling, etc.
To reduce the adverse effects caused by electromagnetic
interference, please pay attention to the following:
1、The power supply system takes necessary measures
against grid interference;
