Fig. 2 is the structural representation of the utility model embodiment 2.
Among the figure: 1 button locking mechanism, 21 first button spring, 22 second button spring, 3 moving contacts, 4 fixed contacts, 5 shells, 6 movable contact springs, 71 resistance, 72 leads, 73 elastoresistance sheets.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment 1
As shown in Figure 1, a kind of resistance step-down arc extinguishing push-button switch, comprise button locking mechanism 1, button spring, moving contact 3, fixed contact 4, shell 5 and resistance mechanism, described fixed contact 4 matches with moving contact 3, fixed contact 4 is fixed in the shell 5, moving contact 3 is installed in the shell 5 by movable contact spring 6, and moving contact 3 is driven by movable contact spring 6 has the second place that contacts primary importance and be separated with fixed contact 4 with fixed contact 4;
Described button spring 2 has two, and wherein first button spring, 21 1 ends connect button locking mechanism 1 other end and connect movable contact spring 6;
Also include resistance mechanism, described resistance mechanisms in series is between moving contact 3 and fixed contact 4, the fixedly connected fixed contact 4 of one end of resistance mechanism, the other end is a free end, conducting when moving contact 3 moves between the primary importance and the second place or arrives primary importance disconnects when moving contact 3 is positioned at the second place.
In the present embodiment, described resistance mechanism is a resistance 71 and a lead 72, and resistance 71 is connected between second button spring 22 and the fixed contact 4 by lead 72.
When work
When closed: press the button locking mechanism 1, movable contact spring 6 drives moving contact 3 and moves downward, and movable contact spring 6 at first contacts second button spring 22, by resistance 71 and lead 72 conducting moving contacts 3 and fixed contact 4; Moving contact 3 continues to move downward then, finally contacts directly conducting with fixed contact 4.Electric current just by the step-down conducting of resistance mechanism, pressed two stages of variation to carry out before complete conducting like this, produced electric arc and can be reduced or not have the electric arc generation, so be not easy to burn out switch.
