Description

Patent Invention (PI) DESCRIPTIVE REPORT: SELF-TIMED ELECTRONIC SWITCH.

[001] The Patent of Invention (PI) of an SELF-TIMED ELECTRONIC SWITCH aims to develop an electronic device, electronic timer switch, which turns on and off lamps by touching a sensor that has the Auto shut-off function, eliminates installation of automation centers and programming of complex touches, facilitating the use and installation, making the final cost more affordable.

[002] Developed with simple, easy-to-buy electronics, turns the ambient light on and off, and if the light is forgotten on, the switch turns off by itself, preventing lights from being left in environments with no one present, avoiding unnecessary power consumption , reducing cost to the consumer and impact on the country and the environment.

[003] Demands for technologies to reduce the cost of electricity have been demanding improvements in methods and techniques that allow better efficiency in these processes.

[004] There are currently known in the market, switches used in everyday homes and businesses that turn on and off manually and automatic systems that demand a very high cost for electronic shutdown, making access to the general population difficult. Another way found is the Presence Sensor which has the inconvenience of being very costly, yet not suitable for environments where people need to stay, such as the bedroom, keeping the lights on.

In view of the problems encountered in the state of the art and in order to overcome them, the Patent of Invention (IP) was developed, constituting an electronic switch with timed self-disconnection, in order to promote disconnection. automatic light bulbs that are forgotten access and reduce the consumption of electricity.

[006] The Patent of Invention (PI) of a SELF-TIMED ELECTRONIC SWITCH was conceived with the intention of bringing advantages to the household and commercial electrical devices and accessories industry in the field of electrical and new installation finishing. technologies, having been found that there is no equipment equal to or similar to the switch that meets the need to turn on and off the light when desired and if left on auto off with a simple time programming at a predetermined time.

[007] The basic principle of the SELF-TIMED ELECTRONIC SWITCH consists of a touch sensor driven electronic device, LED function indicator display, with three operating modes: STAND BY, ON and AUTO OFF, with three times for the Auto power off: "TEST" 5 seconds, "15 MINUTES" and "30 MINUTES" with 2% tolerance for more or less time. It works on 110V to 240V automatic AC mains, installed in a standard box of 4X2 residential and commercial building lighting switches, with relay isolated mains activation. Turns on and off any type of single and parallel light bulb, which is powered by 110 volts up to 400 watts, 220 volts up to 800 watts.

[008] The attached figures show the SELF-TIMED ELECTRONIC SWITCH, where in FIGURE 1 we have the front mounted view of the SELF-SWITCHED ELECTRONIC SWITCH, with 4X2 mirror panel (1), touch sensor (2), set screws mirror (3), operating mode display (4).

[009] FIGURE 1.1 shows the side view of the assembled equipment, with the 4X2 mirror panel side (5), side view touch sensor (6), PCB (PCB) and protective plastic enclosure in side view (7).

[010] In the operation of the switch its function is to turn the ambient light on and off by touching the sensor (2) and consequently the display (4) by the user. The device operates with timed auto shutdown and LED visual information of the operating states: STAND BY, ON and AUTO OFF. In STAND BY mode with the ambient light off, the touch sensor (2) display (4) is illuminated by the location and operating mode led, with specific color ("STAND BY" color), when activated by a user touch sensor (2) and display (4), the ambient light turns on and the display changes color ("ON" color) automatically activating the timer. If in (ON) mode the sensor is touched again, the device turns off the ambient light and returns to STAND BY mode, turning off the timer.

[011] If not toggled again, the switch remains on for a predetermined time that is selected by jumper (short conductor used to connect two points of an electronic circuit) to time selection on plate (10), and connected in "TEST" mode the time is 5 seconds, in "15/30" the time is 15 minutes and removing the jumper the time will be 30 minutes with 2% tolerance for more or less time. At the end of the selected time the timer will automatically turn off the ambient light and indicate on the sensor / display a third led color ("AUTO OFF" color) indicating that the auto off mode has been activated and the ambient light has been turned off by the electronic switch. .

To return to STAND BY mode simply touch the sensor once. To reconnect you must touch the sensor / display again and the light comes on, the timer restarts and the cycle repeats.

[012] FIGURE 2 shows the exploded perspective view, describing the internal and external components of the switch: the mirror panel (1); touch sensor (2); operating mode indicator display (4); fixing screw (3); fixing screw hole (13); sensor / display mounting hole (14), plastic PCI mounting spacers (15); operating mode indication LEDs (16); hole for fastening plastic spacers (17); printed circuit board, PCI (18); access hole for auto-off time selection jumpers (19); wire passage hole of the external electrical connection (20); PCI Protective Plastic Case (21); lamp wire connection pad (PHASE / LAMP); circuit power lead connection pad (PHASE / NEUTRAL) (23).

[013] The electronic circuit board (PCI) (18) is fitted through the holes (17) of the plastic spacers (15) that are fixed to the mirror panel (1) of plastic material. The electronics board has two centrally positioned LEDs (16) for projecting light onto the display (4) of translucent plastic material mounted inside the metal sensor (2), forming the switch actuation button called the "display sensor", which is fixed to the front center of the 4X2 mirror panel (1). The electronic circuit / board (18) is housed in the plastic housing (21) that isolates and protects the electronic components. The housing (21) has a jumper access hole (19) for selecting the auto shutdown time, and a through hole (20) for the wires of the external electrical connection (22; 23). The switch is fixed by the standard 4X2 housing screws (3) in the building, residential and commercial electrical installations in the lighting control of the room lamps.

[014] FIGURE 3 shows the block diagram of the device's electronic circuit: SENSOR (2) connected to the display (4) on the 4X2 mirror panel (1) to be touched by the user. CONTROL 556B (9) Turns the TIMER on and off in the three operating modes: "STAND BY", "ON" and "AUTO OFF; TIMER 556A SELECTOR (10) performs the timed relay (12) which turns the lamp on and off. , according to the selection of jumpers (10), RESET (11) CONTROL intermediate circuit (9), to reset the operating time of "TIMER" (10), RELE (12) triggered by "TIMER" (10) executes the On and off function of the lamps through their internal contacts, providing the isolation of the circuit from the mains to be activated and SOURCE (8) provides full wave direct current, which regardless of the AC input voltage, keeps the circuit stabilized at 12V DC.

[015] FIGURE 4 refers to the Installation scheme: where the auto off time selection jumper (10) has two positions, 5 second "TEST" jumper for auto off (10a), jumper on "15 / 30 "15 minutes and 30 minutes for auto power off (10.b). Demonstration of mains connection wires (24) FASE-F1 127 / 220V (24a), neutral point F2 (24b), lamp and parallel lamp (25) and wiring diagram of lamps (26), lead wire connected the top phase (26a), followed by the phase-connected conductor wire (26b), return lamp conductor wire (26c) and neutral or phase 2 conductor wire (26d).

[016] The load capacity and rated voltage on the Mains is variable in Phase 1 of 127/220 V - Phase 2 refers to the neutral point. The capacity in watts ranges from 127 V - 400 w and 220 V - 800 w.

[017] In the wiring diagram, it can be connected together with the phase supplying the lamps or in a different phase. You have the option of connecting one or more lamps in parallel to the limit power. The selection of the auto shutdown time is made by the jumpers (10) and if it is set to "TEST" it will turn itself off in 5 seconds to check the operation of the system, if it is set to "15/30" it will turn off in 15 minutes and removing it. The auto jumper shuts off in 30 minutes with 2% tolerance for more or less time.

[018] The device consists of an electronic board with 556 mono stable timer integrated circuit and transistors. The lamp comes on relay (12) and the auto off time is set by the time selection jumpers (10).

[019] The switch operates on the 110V to 240V automatic AC mains and the 12 volt DC electronic circuit.

[020] In the description of the electronic operation of the self-timer electronic circuit breaker circuits, the main component is integrated circuit 556, dual timer in stable mono configuration. FIGURE 5 demonstrates that the activity applied in this circuit was to be able to join the two timers of the integrated circuit so that 556A (a) performs relay timed actuation (b) and the other named 556B (c) performs 556A shutdown ( a) ahead of time, when desired. According to 556 integrated circuit datasheet, once the integrated circuit timer is activated in the mono-stable configuration, its output (d) goes to high level and remains so for the determined time obtained by calculating the formula where time = (1,11.rc) divided by 60, and to return to the low level ahead of time, reset the reset port (e). The need was to be able to do this on the "SELF-TIMED SELF-SWITCH" with just one push-button, one-touch lights up, another ring goes off, no auxiliary mechanical switches, and no software-programmable components that compromise mounting space on 4X2 box with increased costs.

[021] For simplified, unprecedented and inexpensive application, to reset the timer, on / off with only one button, the tripping (f) of the two timers is synchronized, performing the pulse coupling (g) for the reset command ( e) 556A (a) at an exact time determined by R20 and C20 from the output of 556B (g) through the flip-flop circuit called "RESET" circuit (h) as described below.

[022] When connecting the circuit to the mains (i) capacitor C1, diodes D1 and D2 rectify the positive peaks of alternating current, zener diodes Z1, Z2, Z3 and Z4 rectify the negative peaks by stabilizing with capacitor C2 the DC current. at 12 volts and supplies all other circuits (j).

[023] With the "STAND BY" circuit and the ambient light off, the "TIMER" stage (a) formed by the 556A mono stable integrated circuit is reset to level 0V at pin 4 (reset) (e), which is generated by the circuit "RESET" (h) formed by transistors T20 in saturation state and T21 in cut state depolarizing the cathode of LED20 (k) remaining off, thus keeping the output pin 5 (d) with level 0V, putting T1 ( transistor drive) (l) in cut-off depolarizing the "RELE" K1 (b) being in the normally open state, but polarizes the anode of LED1 (m) keeping lit indicating in the display (4) the STAND BY mode, ambient light off .

[024] When the sensor (2) display (4) is tapped, the "SENSOR" circuit (n) formed by R10 (1M), R11 (3.9M) and C10 sends a clock on pins 6 and 8 (Trigger) (f) of the IC 556, the "CONTROL" circuit (556B) (c) activates its R20 and C20 timer at a very fast time - less than 1 second, generating a positive pulse on the output (pin 9 ) (g) at the base of transistors T20 and T21, "RESET" (h), through diode D20, D21, C22 and C24 which changes state causing T21 to saturate by polarizing the cathode of LED20 (k) keeping lit as indicated In the display (4), the "ON" mode and the T20 shuts off by raising the voltage level on pin 4 (e) of the 556A "TIMER" by exiting the reset state, changing its output, pin 5 (d), to high level causing T1 (l) to go into saturation by biasing the "RELE" (b) that closes the contacts by turning on the lamp while at the same time depolarizing LED1 (m) keeping it off at the time that is determined by the "TEST" jumpers, " 15 / 30MIN "(o) together with R12, R13, R14 and C11. If before the set time the sensor is touched, the "CONTROL" stage (c) again generates a positive pulse at the output (pin 9) (g) at the base of the T21 that cuts off by depolarizing the LED20 cathode (k). which goes out and T20 goes into saturation state by grounding the reset pin (e) of the "TIMER" that goes to level 0V at the output (pin 5) (d) putting T1 (l) in cut and depolarizing the "RELE" (b) polarizing the LED1 (m) that lights up indicating in the display (4) the status of "STAND BY" and the lamp is turned off.

[025] If the sensor is not touched, after the time determined by the time selection jumpers (o) together with R12, R13, R14 and C11 the TIMER (556A) (a) turns off the output (pin 5) ( d) cutting T1 (l) off by depolarizing RELE (b) and polarizing LED1 (m) which remains lit simultaneously with LED20 (k) indicating on the display the color tone formed by the two LEDs that the device is in mode. "AUTO OFF". The depolarized RELE (b) opens the contacts, turns off the lamp, and remains in this mode until the sensor (n) is triggered again by causing the "CONTROL" (c) to send a pulse to the T20 and T21 which changes state again by depolarizing LED20 ( k) which turns off, takes the TIMER (a) from reset (e) by setting it to "STAND BY", for the cycle to be restarted again.
