Further technical scheme is: for guaranteeing button and push rod reset, button is set to Self-resetting button.
Further technical scheme is: described touch-switch, push rod and installing hole are respectively one, and touch-switch is opened for self-locking
Close.Described button is pressed, button presses silica gel sheath by push rod, silica gel sheath deformation touches touch-switch, leads to touch during use
Switch, output services electric current or working signal.After decontroling button, touch-switch works on.When pressing button again,
Touch-switch quits work.This situation coordinates corresponding circuit to be applied to the switching to automobile-used ordinary appliances electric current or signal
Operation, to open and close of car light etc. it is also possible to be applied to dust compared with overall situation, the such as occasion such as flour mill, cement plant is similar to
The operation of the open and close of electrical equipment etc..
Another technical scheme is: described touch-switch, push rod and installing hole are respectively two, and touch-switch is opened for Self-resetting
Close, can be specifically Self-resetting moving seesaw-type button.One end of button is pressed, button passes through a push rod and presses silica gel during use
Set, silica gel sheath deformation touches a touch-switch, leads to the work of this touch-switch, output services electric current or working signal, such as car
The rising signals of window are so that vehicle window rises.When decontroling button, touch-switch automatically resets, and stops output services electric current or work
Signal, such as vehicle window stop rising；The other end of pressing button, button presses silica gel sheath by another push rod, and silica gel sheath deforms
Touch another touch-switch, lead to this another touch-switch to work, export contrary operating current or working signal, such as car
The dropping signal of window is so that vehicle window declines.In the same manner, when decontroling button, vehicle window stops declining.This situation coordinates corresponding circuit
It is applied to the lifting to vehicle window etc. it is also possible to be applied to the larger environment of dust, such as the occasion such as flour mill, cement plant is similar to
The control of the lifting of electrical equipment, opening and closing etc..
