Abstract
The utility model discloses a kind of switch effectively preventing impulse current voltage, it comprises shell, button, plug-in strip and negative tempperature coefficient thermistor.The output of negative tempperature coefficient thermistor access switch internal, negative tempperature coefficient thermistor, push-button switch are packaged into an entirety.This kind of switch effectively can suppress impulse current voltage during switch opens, and structure simple, be convenient to produce.
Description
Technical field
The utility model relates to a kind of switch, is specifically related to a kind of switch effectively preventing impulse current voltage.
Background technology
At present, market there is no a kind of switch designs that effectively can suppress impulse current voltage.Therefore inventor to envision design a kind of novel switched, can effectively prevent impulse current voltage, solve the deficiency of existing switch.
Utility model content
The purpose of this utility model is to provide a kind of switch effectively preventing impulse current voltage, and this construction of switch is novel, easy to use.
To achieve these goals, the technical solution of employing is the utility model:
A kind of switch effectively preventing impulse current voltage, comprise shell, button, plug-in strip and negative tempperature coefficient thermistor, described button is positioned at above plug-in strip, described negative tempperature coefficient thermistor is arranged on the output of plug-in strip, and negative tempperature coefficient thermistor, plug-in strip and button are packaged into an entirety by shell.
The beneficial effects of the utility model are
This kind of switch, comprises shell, button, plug-in strip and negative tempperature coefficient thermistor, and power supply connects moment, and impulse current voltage is comparatively large, and now the resistance of negative tempperature coefficient thermistor is comparatively large, can impulse current voltage in limiting circuit.When larger electric current flows through negative tempperature coefficient thermistor, resistance heating makes resistance reduce, and circuit recovers normal operating state.
Accompanying drawing explanation
Fig. 1 is the structural representation of switch.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
As shown in Figure 1, a kind of switch effectively preventing impulse current voltage, comprise shell 4, button 2, plug-in strip 3 and negative tempperature coefficient thermistor 1, described button 2 is positioned at above plug-in strip 3, described negative tempperature coefficient thermistor 1 is arranged on the output of plug-in strip 3, and negative tempperature coefficient thermistor 1, plug-in strip 3 and button 2 are packaged into an entirety by shell 4.
This kind of switch, in use procedure, when button 2 is pressed, plug-in strip 3 closes, and the impulse current voltage in circuit can become large instantaneously, and now the resistance of negative tempperature coefficient thermistor 1 is comparatively large, can suppress the impulse current voltage in circuit.When negative tempperature coefficient thermistor 1 flows through larger electric current, resistance heating and the resistance of resistance is diminished, circuit recovers normal operating conditions.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned citing, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection range of the present utility model.
Claims (1)
1. one kind effectively prevents the switch of impulse current voltage, it is characterized in that, comprise shell, button, plug-in strip and negative tempperature coefficient thermistor, described button is positioned at above plug-in strip, described negative tempperature coefficient thermistor is arranged on the output of plug-in strip, and negative tempperature coefficient thermistor, plug-in strip and button are packaged into an entirety by shell.
