Power on behavior is determined by the resistance at point A. If there is resistance at point A, the output closes after power on. If there is no resistance at point A, the voltage is output directly after power on. Touch type single key bistable switch that can be set to self locking or inching mode. Maximum sensing distance can reach 8 mm, suitable for touch switch control of acrylic panels, casings and veneers. Operating voltage is DC 3 30 V and the maximum output current is 2.5 A. It can directly drive various low power electrical appliances, lamp belts, LED lamps and other electrical appliances. Applications and use scenarios Cabinet and display lighting: install behind acrylic panels or veneers to enable touch control for lighting with a reliable self locking or momentary mode. Furniture and architectural accents: integrate into furniture or decorative enclosures to switch LED lighting or small power devices through a touch point up to 8 mm away. DIY and equipment enclosures: use in hobbyist projects or small enclosures that require a compact touch switch with simple wiring and direct driving capability for LED strips and other low power loads.
