Key benefits and why you need it Flexible poweron behavior: output state at poweron is determined by resistance at point A. If resistance is present at A, the output closes after power on; if no resistance at A, the voltage is output immediately on power on. Wide compatibility and strong drive: works with DC 330V and can deliver up to 2.5A, allowing direct control of various lowpower appliances, lamp belts, LED lamps, and similar loads. Precise touch control with selectable operation: a touchtype singlekey bistable switch that can be set to selflocking (latching) or inching (momentary) mode to fit different usage scenarios. Easy, broad applicability: sensing distance up to 8 mm enables convenient operation through acrylic panels, casings, and veneers. Product features Power supply: DC 330V Maximum output current: 2.5A Load types: directly drives lowpower electrical appliances, lamp belts, LED lamps, and similar devices Switch type: touchtype singlekey bistable switch Modes: selflocking (latching) or inching (momentary) Sensing distance: up to 8 mm Ideal for touch switch control on acrylic panel casings and veneers 23 practical use scenarios Display case lighting: place the switch behind an acrylic panel to control LED strip lighting. Set to selflocking to turn the lights on with a tap and off with another tap, keeping the front panel clean and seamless. Undercabinet or backlighting: use in a small enclosure to control LED strips. The inching mode can be used for momentary operation, such as briefly lighting a workspace when needed. DIY project enclosure control: integrate into a lightweight project box to switch lowpower devices directly from a touch input, with reliable bistable behavior and a responsive 8 mm sensing distance.
