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
