Touch type singlekey bistable switch with flexible operation and strong compatibility Key benefits Two operating modes: selflocking (latching) or inching (momentary) mode to match how you want to control loads touch sensing distance up to 8 mm for reliable use on acrylic panels, casings and veneers Simple direct drive for lowpower devices and lighting, reducing control complexity Poweron state selectable via presence or absence of resistance at terminal A for flexible startup behavior Specification and performance Type: touch type singlekey bistable switch Modes: selflocking (latching) or inching (momentary) Sensing distance: up to 8 mm Power supply: DC 3 to 30 V Maximum output current: 2.5 A Load compatibility: directly drives various lowpower electrical appliances, LED lamps and LED strips Output on powerup: state can be configured by resistance at terminal A If resistance is present at terminal A, the output closes after power on If no resistance is present at terminal A, the voltage is output directly after power on Applications: designed for touch switch control in acrylic panels, casings and veneers Recommended use scenarios Scenario 1: Touchactivated LED lighting behind an acrylic cabinet door. Use the selflocking mode to toggle lights on/off with a single touch, and wire terminal A to set the desired poweron behavior. Scenario 2: Lighted display panel or sign with an acrylic face. Utilize the 8 mm sensing distance for easy, accidental activation and control a lowpower LED strip up to 2.5 A. Scenario 3: Small furniture lighting or desk lamp control. The device powers directly from 3–30 V DC and can drive LED lamps or similar loads without additional relays. Notes Suitable for integrating into installations that use acrylic panels, casings and veneers Ensure supply voltage and current stay within the DC 3–30 V and 2.5 A limits Wiring should preserve terminal A configuration to achieve the intended poweron output behavior
