First of all, in the case of early purchase, it is necessary to consider the application requirements and application frequency, select the switch with the best materials and processing technology, and pay attention to the flame retardant grade, corrosion resistance, more beautiful and safer.
Secondly, in relatively wet and cold areas such as restaurants, kitchens and toilets, lifting the cover of the switch will not only prevent oil and water stains, but also make the application more secure. The switch in the bathroom should be installed with an aspect ratio of 150-160cm to prevent water vapor on the road and its daily water from splashing on the surface of the switch. Naturally, there is no need to block daily applications. The switch in the restaurant kitchen proposes to avoid the stove two meters or more to prevent fire accidents.
In addition, in the entire application process, try to avoid unnecessary switch gestures, and the little kids who fancy at home don't have to let them use switches as small toys. Due to constant switching, the inner core will become more brittle, and the actual operation of the switch will fail.
In the end, if the switch turns yellow and shows old, and the oil that cannot be removed is adhered, the environmental protection sponge can be wetted with cold water and dried, and the marks can be erased by arcing, and then wiped clean with a dry cloth. If the actual effect is not very good, try to use a dry cloth dipped in a small amount of ethanol with a lower concentration (70%-75% concentration value) to scrub. Do not clean with water, because cleaning with water will not only leave water stains, but also There is a risk of electric shock.
You can also use a soft toothbrush to moisten it with a little whitening toothpaste, brush it back and forth on the stain, and then wash it off with a clean towel. Or use an eraser to wipe off the stains, which is a labor-saving and cost-effective method.
