<p>Touch type single key bistable switch, which can be set to self-locking or inching mode. The maximum sensing distance can reach 8mm, which can be widely used in the touch switch control of acrylic panels, various casings and veneers.</p> <p>The working voltage is DC 3 - 30V DC, and the maximum output current can reach 2.5A. It can directly drive low-power electrical appliances, lamp belts, LED lamps and other electrical appliances.</p> <p>(There is or resistance by default) select the output state after power on. When there is or resistance at point a, the output is closed after power on. When there is no 0r resistance at point a, the voltage is directly output after power on.</p> <p>Adjust the distance of touch sensing. The default is the maximum distance (7-8mm). If you want to reduce the sensitivity, you can add a capacitor of 1 - 50pF according to the actual situation. The smaller the capacitor, the higher the sensitivity, and the larger the capacitor, the lower the sensitivity.</p> <p>Hign-concerned Chemical:None</p> <p>Model Number:Switch sensing module</p> <p>Operating Temperature:-40-+85\u2103</p> <p>Dissipation Power:2.5A</p> <p>Supply Voltage:3-30V</p> <p>Application:Computer</p> <p>Type:B:3-wire Blue Light</p> <p>Colour:As Shown</p> <p>Material:PCB</p> <p>Package Contents:</p> <p>1 * module</p> <p>1 * power cord</p> <p>1 * double-sided tape</p> <p>Only the above package content, other products are not included.</p> <p>Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
