Poweron output state selection by resistor at point A. If a resistor is connected at point A, the output is closed after poweron. If there is no resistor at point A, the output voltage appears at the output immediately after poweron. Operating voltage and drive capability. Working voltage: DC 3–30 V. Maximum output current: up to 2.5 A. Directly drives various lowpower electrical appliances, lamp strips, LED lamps, and other devices. Touchtype singlekey bistable switch. Can be set to selflocking (latching) or inching (momentary) mode. Maximum sensing distance up to 8 mm. Widely suitable for touch switch control on acrylic panel casings and veneers. Use scenarios In a display cabinet or furniture with an acrylic panel, use the touch switch to turn LED lighting on and off without mechanical buttons. In decorative panel or veneer installations, implement a touchactivated control for LED strips or lowpower lamps with a clean, seamless appearance. In small kiosks or showcases, use the bistable touch switch to control lighting or auxiliary devices with a reliable, contact interface.
