Abstract
The utility model discloses a switch with a key ring, wherein the switch comprises a soleplate and a switch arranged on the soleplate, the switch further comprises a key ring arranged on the lower end of the switch, a weight sensor is arranged at the connecting site of the key ring and the soleplate, an LED (Light Emitting Diode) lamp bank is arranged at the edge of the key ring, the weight sensor is connected with the input end of the controller, the LED lamp bank is connected with the output end of the controller, and a sound sensor is connected with the controller. The key ring is arranged to plane keys so as to avoid the condition of failing to find the key when going out, the LED lamp bank is also arranged to conveniently find the switch under a dark environment, and meanwhile, the sound sensor detects a sound signal to turn on the LED lamp bank to prompt the user to take the key so as to avoid forgetting the key.
Description
Technical field
The utility model relates to a kind of switch with key chain.
Background technology
Switch can make open circuit, makes current interruptions or make its electronic component that flows to other circuit, is must indispensable electricity piece in the family life.A lot of people can leave about key to family is later, can not find key when causing going out and anxiety is perhaps gone out and left behind key, cause entering the situation at door.Switch in the market is not with key chain, and is not easy to find the accurate location of switch the environment user of dark.
Summary of the invention
Main purpose of the present utility model is to provide a kind of switch with key chain, is provided with key chain, can containing key, also be provided with LED lamp group, and can under the environment of dark, find easily switch, and prompting user is taken key away.
A kind of switch with key chain of the present utility model, comprise base plate, and be arranged on switch on the base plate, it is characterized in that: also comprise the key chain that is arranged on the switch lower end, described key chain and back plate connections are provided with the weight induction device, and described key chain edge is provided with LED lamp group, and described weight induction device connects the controller input, LED lamp group connects controller output end, and a sound transducer is connected with described controller.
Described controller adopts single-chip microcomputer.
Switch with key chain of the present utility model has the following advantages: be provided with key chain, can containing key, can not find key when avoiding going out, also be provided with LED lamp group, can under the environment of dark, find easily switch, detect voice signal by sound transducer simultaneously, LED lamp group is lighted, prompting user is taken key away, has avoided forgeing.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing:
Fig. 1 is that this practicality is with the structure chart of the switch of key chain.
Embodiment
As shown in Figure 1, a kind of switch with key chain of the present utility model, comprise base plate 1, and be arranged on the switch 2 on the base plate 1, and be arranged on the key chain 3 of switch 2 lower ends, described key chain 3 is provided with weight induction device 4 with base plate 1 junction, described key chain edge is provided with LED lamp group 5, and described weight induction device 4 connects the controller inputs, and LED lamp group connects controller output end, one sound transducer 6 is connected with described controller, and described controller adopts single-chip microcomputer.
The user enters indoor, and sound transducer 6 is sent to controller after detecting voice signal, is lighted by controller control LED lamp group, makes the user find easily switch under the environment of dark; By key is placed on the key chain 3, make weight induction device 4 detect the Gravity changer signal and send to controller, controller control LED lamp group 5 is turn-offed.
When the user left, sound transducer 6 was sent to controller after detecting voice signal, was lighted by controller control LED lamp group, is used for reminding user key is taken away, avoided forgeing; After key was taken away, weight induction device 4 detected the Gravity changer signal and sends to controller, and controller extinguishes LED lamp group 5.
Above-described embodiment; it is an example of the present utility model; be not to limit enforcement of the present utility model and interest field, all or technical schemes of being equal to identical with the described content of the utility model claim all should be included in the utility model protection range.
