See more ideas about wooden lamp, wood lamps, lamp design. A standard 741 op amp is employed in the form of a sensitive voltage level switch which subsequently drives the current buffer Q2, a medium current pnp bipolar transistor, thus activating the relay that may be accustomed to switch a device, such as alarms, faucet etc. stream Reply. how i can remove the losess of relay on ON & OFF time induced sparks in relay use on touch sensitive switch. One person found this helpful. A touch sensor can be done in several ways, this is a capacitive approach and doesn't use any dedicated IC, it's based on a operational amplifier or not gate, a counter and a small microcontroller to read the signal. Single Channel Capacitive Touch Sensing IC. But the stability of TTP223N-BA6 is worse than TTP223-BA6’s. �p�����=n����K�z� ���8_Ͽ���LM^��_3������pz�,��!��ÿ����D��y��� \?�B��4��y�q�JS\�?����|�`����8��Y��O������~���&=r{>���?������� �k�m�?����v��w_�f߱fnfz���䠝ވ��d��Q���x�|�\M H�}�X�9�|�y�x�k��|�ķJن�����vw��~]N?·��8Ty��칓�]�����=}_�?���5�>P_^ �'u���?��_���:��bw�K�8� 7K�9�ˏ�3hwa�`3WIgp�������~��ۏW�=�F��%��s�����dM���v�����f/w��K�q��WY%�q� ����:����m�ך�i��Y�{F螻�����v.
