2pcs DC 3V-30V 5V 12V 2A Miniature Capacitive Touch Switch Sensor Module Mini Bistable Button Electronic Control for LED Relay Latch/Inching Trigger Action

The product has been updated, with no changes in size or functionality. The update is as follows: 1 The PCB terminals are soldered with wiring plugs instead of being soldered onto the PCB. The end of the 4pin wire delivered needs to be wired or soldered by the customer themselves, not the plugs. 2. The PCB has added anti-interference resistors to enhance its functionality. Operating voltage: DC 3V-30V, ultra-low standby current 2uA within 5V, operating current: 0-2A, round board diameter 2cm/0.78inch. Operating Mode: Support Latching/Jogging mode (The default state is latching mode: press once to open, and then press once to close); If set in jog mode: There is output when touched, but no output when released. Power-on state: Support power-on boot(direct output voltage) / power-on standby(Default setting, closed output). Power-on boot state: led light on, output voltage = power voltage; In standby state: LED light off, output voltage=0V. The touch sensor switch module and the back of the circuit board are touch-sensitive surfaces, and the double-sided adhesive is very convenient for pasting on the surface of glass, plastic, rubber, acrylic, ceramics and other media. Touch sensitivity adjustment: Maximum sensing distance up to 8mm, If you want to reduce sensitivity, you can add 1-50PF capacitors according to actual usage. The smaller the capacitance, the higher the sensitivity; Suitable for LED light control, support for external relays, power switch, microcontroller etc. low dropout design.
