Dust-proof
Dust on the switch surface will cause electrostatic adsorption,
poor contact of the metal contacts. Although the device itself
has done some measures in anti-static, but when the static
electricity exceeds a certain intensity, it will still cause fatal
damage to the electronic components on the internal circuit
board.
In order to prevent static electricity from affecting the normal
operation of the equipment, please note the following:
1. Regular dust, keep the indoor air clean;
2. Make sure the equipment is well grounded to ensure
smooth transfer of static electricity
Electromagnetic interference
Electromagnetic interference have an impact on the device
capacitance, inductance and other electronic components by
capacitance, inductive coupling, impedance coupling and
other conductive, in order to reduce the adverse effects
caused by electromagnetic interference, please note the
following：
1. Power supply system to take the necessary anti-grid
interference measures;
