Abstract

A type of two-wire low internal voltage drop sensor switch with LED indicator includes a power supply (3), a diode voltage measurement circuit (11) and switch components (12). The diode voltage measurement circuit (11) comprises two diodes connected in parallel in positive and negative directions. There is a booster driver circuit (13) connected on top of the paralleled diodes. The booster driver circuit (13) is connected to the LED. The circuit used in the two-wire sensor switch with LED indicator can collect about 0.7V to 0.8V voltage by means of flow direction conduction of a diode. And by using a booster circuit to provide the LED with a conducting source voltage, it is possible that the LED can be activated by a low internal voltage drop of about 0.7V to 0.8V and larger electric current can pass.

Scope of Technology This new application is a type of sensor switch, and in particular is a type of two-wire low internal pressure drop sensor switch with LED indicator.
Technical Background
Currently the following types of two-wire sensor switches with LED indicators are available: 1. as depicted in Diagram 1, the LED is connected in series to the switch, and the electric current of the switch is restricted by the LED, with an average wattage of 2OmA.
Additionally, an internal pressure drop leads to a drop in connectivity in the direction of the
LED, on average between 2V and 3V. 2. As depicted in Diagram 2, after connection a current-limited resistance in series to the switch LED, it is reconnected in parallel with a stable pressure diode circuit. A rather larger electrical current can be passed, but there is still a
2V to 3 V internal pressure drop; 3. As depicted in Diagram 3, after connection a current-limited resistance in series to the switch LED, it is connected in parallel with a circuit consisting of three serial diodes and a reverse diode. A rather larger electrical current can be passed, but there is still an internal pressure drop of 2.1V to 3 V. The above all has to overcome an internal pressure drop of 2V to 3V in the LED conductivity, and their energy consumption is relatively high.

Pressure measurement circuit and switch components, diode pressure measurement circuit linked to a driver LED by means of a booster circuit. The diode pressure measurement circuit described above consists of two diode components linked in parallel in positive and negative directions. The above-mentioned booster circuit applies discrete components and LC oscillating booster circuit, or utilizes an integrated booster circuit.
Used in two-wire sensor switches with a LED indicator, this new application can collect about 0.7V to 0.8V voltage a by means of flow direction conduction of a diode. And then use a booster circuit to provide the LED with a conducting source voltage, making it possible that the LED can be activated by a low internal pressure drop of about 0.7V to 0.8V and larger electric current can be passed to reduce energy consumption.
