Touch Button Switch Sensor Module - Stable performance with durable construction. The touch switch has a maximum load current of 3A; to avoid damage, keep within 5A. When connected to relay control output, inductive load, or motor, install an absorption loop to protect the circuit. Maximum sensor distance is 8mm; it works best with no obstruction between sensor and finger. - Upgraded four-wire design. The touch mode remains active for up to 8 seconds before automatic reset, providing improved stability and reliability. - Wide application and control options. The module supports a maximum control current of 3A and an output voltage of 30V. It includes A/B/C custom functions to select the output status after switching on, choose lock mode or click mode, and adjust the sensitivity of the touch sensing. - Compact and convenient. With a diameter of 20mm, this module is compact and easy to integrate. It comes with a matching cable, transparent double-sided tape, and a motherboard for easy setup and connection. Use scenarios: - Touch-activated light switch for cabinets, desks, or small appliances. - Control panel for relays or small motors in DIY projects. - Hobby or prototype automation where a discreet, touch-sensitive input is needed.
