Description

A kind of multifunction switch

Technical field

The utility model relates to electronic technology field, is a kind of device realizing carrying out electrical equipment switch control rule by hardware circuit.

Background technology

At present, known appliance switch is except being installed on electrical equipment except with it, and application is exactly at most the switch of electric light the most widely, all can install at least 5 switches in each household resident family, and be used for controlling electric light, ventilating fan etc., a lot of switch also can be installed by classroom.Traditional switch is that 2 gears are pressing, namely opens or closes.This switch is sometimes inconvenient in real life, and as needs of getting up night are turned on light, switch is just inconvenient a long way off, needs additional illumination, sometimes forgets that turning off the light also has needed to make a return journey simultaneously and turn off the light, cumbersome.Also small part switch is had to adopt pyroelectric infrared sensor at present, can by responding to the human body infrared light on and off controlling lamp, when there being people movable in transducer detection range, automatically will lighting illuminating lamp, after going beyond the scope, after a few minutes time delay, closing electric light.But current this switch can not control the light on and off of electric light completely according to the wish of people.As turned on light when user needs light not by day to be fine, because the photosensitive circuit in transducer is judged to be that daytime does not turn on light, then user cannot turn on light, or night, user needed to turn on light for a long time, cannot meet the demands because transducer time delay is shorter.Therefore above two kinds of switches can not meet the life requirement that people improve day by day well.

Utility model content

In order to solve subject matter and the deficiency of existing switch product, the utility model provides a kind of multifunction switch, and this switch, on the basis of the pyroelectric infrared sensor of application enhancements, increases the delay circuit of three gear Push switches and 1 hour.This switch can carry out model selection by three gear Push switches, Chang Kai, normally closed and startup pyroelectric infrared sensor.This switch can solve the light switch problem in life, and for people bring convenience, energy-conserving and environment-protective, are particularly useful for family, the electric light light on and off of classroom and office control.

The utility model solves the technical scheme that its technical problem adopts: common pyroelectric infrared sensor module comprises transducer, delay circuit, photosensitive circuit.Basis is novel to be improved, delay circuit in module is exported control signal end and connects diode forward end and PNP triode, the signal output part of 1 hour additional delay circuit is connected with diode reverse end and PNP triode as a total output control signal.Carry out the mode of operation selection of multifunction switch with the Push switch of three gears, three gear Push switches, pyroelectric infrared sensor module and relay module are interconnected simultaneously.Three gear Push switches are non-self-lock-ing form, namely upwards pressing rear relieving hand downwards can upspring to default location automatically, when three gear Push switches upwards click for selecting normally open, start 1 hour delay circuit simultaneously, electric light Chang Liang, close after 1 hour, as bright in needed electric light to continue, then again click.During three gear Push switch default locations, i.e. centre position, for selecting to start pyroelectric infrared sensor pattern, transducer controls the switch of electric light according to User Activity situation in extraneous light intensity and investigative range.After three gear Push switches press, namely select normally closed pattern downwards, electric light is closed, and starts the short time delay circuit in pyroelectric infrared sensor module, and time delay terminates rear recovery acquiescence, starts pyroelectric infrared sensor pattern.Multifunction switch entirety is measure-alike, compatible good with traditional switch.

The beneficial effects of the utility model are, design realizes a kind of multifunction switch, the light on and off of electric light can be controlled freely according to user intention, as got up night, electric light can be automatically bright, automatic distinguishing after time delay, user can manually select electric light Chang Liangchang to go out and pyroelectric infrared sensor mould pattern, very convenient.Simultaneously this switch outward appearance and size are consistent with traditional switch, and compatibility is good, easy for installation, can be applied to multiple occasion, practical, is particularly useful for family, classroom and office.

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model, the application in embodiment is to control electric light.

Embodiment 1, this example discloses a kind of multifunction switch, in FIG, the signal output part 5 of pyroelectric infrared sensor module 1 is connected with the collector electrode of 8550 triodes, signal output part 5 rear connection 8550 transistor base in series with a resistor of 1 hour delay circuit 2, the signal output part 5 of 1 hour delay circuit 2 and the Enable Pin 6 of the backward end and relay module 3 that are connected diode simultaneously, the emitter of 8550 triodes is connected with the forward end of diode, switch element 4 respectively with pyroelectric infrared sensor module 1, 1 hour delay circuit 2, the Enable Pin 6 of relay unit 3 connects.When pyroelectric infrared sensor module 1 works, after detecting physical activity, signal output part 5 exports high level, relay unit 3 starts, the built-in delay circuit of module is started working, electric light bright and time delay a period of time, when switch element 4 upwards clicks, start 1 hour delay circuit 2, the built-in delay circuit of closing module starting switch unit 3 simultaneously, electric light is bright and time delay recovers acquiescence after one hour, namely pyroelectric infrared sensor module 1 is started, switch element 4 clicks downwards, close one hour delay circuit 2 and relay unit 3, start the built-in delay circuit of module, lights time delay a period of time.

Fig. 2 is the structural representation of this example, and the sensor probe of pyroelectric infrared sensor module 1 divides the surface being installed on switch case 7 with switch element 4, as shown in Figure 2.It is inner that remaining circuit is installed on switch case 7, invisible.When rather dark, pyroelectric infrared sensor module 1 works, in investigative range, physical activity detected, namely turn on electric light, when needs are turned on light for a long time or daytime, well lighted was turned on light, switch upwards can be clicked, turn off the light switch can be clicked downwards as forced.
