Custom Contactless Capacitive Touch Membrane Switch with Ultra-Thin Flexible PET Structure and Waterproof Surface for Smart Appliances
Mingcai Electronics is a professional manufacturer with 15 years of production experience, specializing in the production of capacitive and resistive touch control membrane switches.
Our capacitive touch membrane switch is a new-generation flexible control panel replacing traditional mechanical push-button keypads, manufactured with imported conductive PET film and high-precision capacitive sensing circuit technology.
Different from tactile dome membrane switches, capacitive touch panels realize contactless induction control, no mechanical wear, longer service life and smoother operation experience. We support full customization: custom digital display windows, multi-function touch keys, full-color gradient silk-screen printing, backlight light guide layer, FPC flexible extension cable and double-sided adhesive backing.
Widely matched with refrigerators, washing machines, water heaters, treadmills, shower controllers, medical testing equipment, industrial small instruments and smart kitchen appliances as core operation control interfaces. The ultra-thin flexible structure fits curved and flat equipment housings perfectly, with excellent waterproof, oil-proof and anti-fouling performance suitable for long-term household and industrial environment use.
- Contactless Capacitive Induction Touch: No mechanical metal domes, touch sensing without pressing force, zero wear, service life over 1 million touch operations.
- Ultra-Thin Flexible PET Structure: Total thickness only 0.2~0.6mm, bendable, fits flat and slightly curved equipment shells without gaps.
- Optional Uniform Backlight Design: Add light guide layer for LED backlight, even light transmission without dark spots, clear display in dark environment.
- Waterproof & Oil-Proof Surface Protection: Hard UV silk screen coating resists water splashes, cooking oil, alcohol wiping, printing patterns never fade or peel off.
- Full Customization of Circuit & Appearance: Custom touch key layout, digital display cutouts, gradient color printing, FPC tail length and position according to customer PCB board size.
- Stable Anti-Interference Circuit: Anti-static capacitive circuit design, stable touch response under electromagnetic interference from household appliances.
