The operating principle of capacitive membrane switches primarily relies on changes in capacitance. When a human body or other conductive object contacts the switch's sensing area, it alters the capacitance value within the switch. This change in capacitance is detected by the circuit and converted into an electrical signal, thereby triggering the switch's action. Consequently, capacitive membrane switches require no physical pressing or mechanical movement, exhibiting characteristics of high sensitivity and rapid response.
High Sensitivity and Stability
Utilising capacitive sensing technology, it accurately detects minute touch gestures, enabling non-contact operation through over 20mm of insulating material. Unaffected by environmental factors such as weather or humidity, its stability surpasses that of traditional mechanical buttons.
Extended Lifespan and Waterproof Properties
The absence of mechanical contact structures ensures theoretically infinite lifespan with zero maintenance requirements. Simultaneously offering moisture, dust, and oil resistance with robust sealing, it remains suitable for demanding environments.
Versatile Design and Compatibility
Supports customisation with glass, plastic, and other panel materials to integrate seamlessly into diverse product aesthetics. Strong compatibility with single-wire/neutral-wire power supply configurations makes it adaptable for smart home systems, appliances, and similar applications.
Interference Resistance and Low Power Consumption
Employs neutral-live power supply technology for safety and reliability; capacitance variation detection algorithms filter interference signals, achieving lower power consumption than traditional mechanical buttons.
Optimised Touch Experience
Supports operation with wet hands; panels are washable without damaging characters; LED backlighting enhances night-time operability.
