Embodiment Construction

[0025] FIG. 3 shows an overall schematic diagram of the electronic switch of the present invention. As shown, the present invention utilizes only two lines L1 and L3. FIG. 3 only shows the construction of the electronic switch as indicated by dashed lines in FIGS. 1 and 2 . Since connections to external power lines and wiring related to lamps are the same as those of FIGS. 1 and 2 , descriptions of these items will be omitted.

[0026] Referring to Fig. 3, the configuration of the present invention will be described. The present invention is an electronic switch having first and second wires connected across a light for electronically turning the light on and off. Electronic switches consist of the following parts:

[0027] a power supply 100 comprising a pair of diodes D1, D2, each of which is inserted in series between first and second lines L1, L3, and both of which are connected in parallel with opposite polarities; a transformer TRANS 1, which For boosting the voltage...

Abstract

The present invention provides an electronic switch which overcomes the problem in installation of the conventional 3-line electronic switch and the problem in power consumption and power stability of the conventional 2-line electronic switch by two input lines. The switch comprises a) a power supply including a pair of diodes, each of which is inserted in series between the first and second lines, and both of which is connected parallel in the opposite polarity; a transformer for raising the voltage appearing across the diodes; a first rectifier for rectifying the raised AC into DC; a second rectifier for rectifying the current from the first line, when the first and second lines are disconnected due to the lamp-off, b) a voltage regulator, including a means for suppressing abnormal rise in the output voltage of the voltage supply, and c) a relay drive including a relay which is operated by DC voltage from the voltage supply, whereby the relay is a self-holding relay that once activated by the current flowing the coil, the relay remains the activated state even though the voltage is removed.

Description

technical field [0001] The invention relates to an electronic switch. More specifically, the present invention relates to an electronic switch for obtaining power for electrical appliances and for minimizing power consumption. Background technique [0002] Switches for turning lights and appliances on and off have recently evolved into remote controls for convenience and safety, or electronic switches operated by electronic circuits. [0003] Conventional 3-wire electronic switch [0004] A conventional light switch has two terminals where if the terminals are connected the light is on and vice versa. Electronic switches for lamp applications, on the other hand, consist of a combination of relays and SCRs or triacs. A typical schematic diagram of an electronic switch is shown in FIG. 1 . The controller 10 is used to control and drive the relay RY1. The controller 10 can be configured to automatically turn the lights on in the morning with the help of a built-in clock, o...
