In electronic scales, membrane switches act as control switches. Users can control various functions of electronic scales by operating membrane switches, such as power on, power off, peeling, zeroing, calibration and printing.
Electronic scales use membrane switches as panels, which have the following advantages:
1. Waterproof and dustproof: membrane switches have good waterproof and dustproof properties, which can prevent electronic scales from being damaged by moisture and dust during use, thereby ensuring the normal operation of electronic scales.
2. Stable performance: membrane switches have stable performance, which can ensure that electronic scales maintain stable accuracy and reliability during long-term use.
3. Long life: membrane switches have a long service life and can withstand a large number of key operations, thereby reducing the frequency of maintenance and replacement.
Structural features:
The main types of membrane switches include hard membrane switch panels and soft membrane switch panels. Its structure is usually composed of a rigid or flexible printed circuit board as the base, with buttons with or without feel installed, and then covered with a plastic (PC, PET, etc.) film panel printed with colorful decorative patterns. This structure makes the membrane switch have both switch function and decorative function.
Post-maintenance:
The membrane switch is an important part of the electronic scale operation interface. In terms of maintenance, it is necessary to regularly check whether the membrane switch buttons are sensitive and whether the surface is clean. If the membrane switch is found to have problems such as button failure or surface dirt, it needs to be cleaned or replaced in time.
