An electronic touch lamp control is used to convert a lamp to touch-sensitive use. It includes a circuit housing and a light bulb insertion socket mounted. A touch sensing circuit in the circuit housing has a self-compensating subcircuit to eliminate the effects of slower changing ambient capacitance of the lamp in order to detect touching of the lamp by monitoring rapid changes in lamp capacitance. A spring contact connected to the circuit is attached to the circuit housing and projects along a side for placement between the circuit housing exterior and the interior surface of the light socket shell and in electrical contact with a conductive portion of the light socket shell when the circuit housing and insertion socket are installed within the light socket shell.
Electronic transformers are transformer used in electronic applications. These are used to supply power, transmit signals, and establish voltage isolation between circuits, sense voltage and current levels. It also provides impedance matching, and filtering. The types of electronic transformers include power, pulse, instrument, and current, switching, inverting and impedance matching transformers.
Electronic Vacuum Sensor is capable of detecting a relatively low vacuum pressure of about 0.04 to 0.05 inches of water. The power source is coupled to the contact blade. The LED is activated by a high-sensitivity vacuum switch. A thin flexible diaphragm extending longitudinally through the channel between the second contact blade and the lower surface of the channel. The pressure travels along the diaphragm and raises the diaphragm.
