When buying, you will receive the assembled (soldered) electrical module. We make an inspection on the working capacity of this device.

The device is a capacitive touch sensor and can be used to replace conventional tactile switches or as a standalone unit to control LED strips or similar loads, depending on the modification.
The sensor operates through non-metallic materials such as plastic, cardboard, plywood, or glass. This feature can be used to create hidden or protected control elements.
Place the module in a sealed enclosure or hide it behind a device’s front panel — the button will detect the presence of a finger even through a dielectric layer up to 4 millimeters thick.

The sensor element is based on a touch pad detector IC, which analyzes changes in the capacitance of the sensor. The sensor itself is implemented as a foil pad on a printed circuit board, covered with a protective solder mask. When a finger touches or approaches the pad within a distance of up to 10 mm, the device is triggered.

Non-latching models: when touched, the module's MOSFET switch turns on (conducts), and when the touch is released, the transistor returns to its off (non-conducting) state.

Latching models: when touched, the module's MOSFET switch turns on and remains on even after the touch is released. A subsequent touch switches the transistor back to its off state.
