On be provided with a fixed contact, original state, the movable contact on one of springboard is in contact with fixed contact, when sliding slider,
Another movable contact starved on the springboard is in contact with fixed contact.
In above-mentioned technical proposal, it is preferred that further include magnet, the magnet has two pieces, and one block of magnet is arranged two
Right side on two fixed touching plates is arranged in the fixed contact middle position of a fixed touching plate upper left side, another block of magnet
Fixed contact middle position.
In above-mentioned technical proposal, it is preferred that further include a handle pushing block, the handle pushing block is rotatably connected on the hand
On handle, confined planes are provided on the shell, when rotating the handle to certain angle, one end of the handle is stuck in the limit
On plane.
In above-mentioned technical proposal, it is preferred that be provided with diode between two fixed touching plates.
In above-mentioned technical proposal, it is preferred that further include push rod spring, the push rod spring covers on the push rod, described
One end of push rod spring is resisted against the end that push rod protrudes into described shell one end, and the other end of the push rod spring is resisted against described
On shell.
In above-mentioned technical proposal, it is preferred that the driving lever includes driving lever spring and the support frame positioned at driving lever both ends of the spring,
It is provided with card slot on support frame as described above, the connecting rod that the card slot matches is provided on the push rod and the sliding block, described
Under the action of driving lever spring, the connecting rod is caught in the card slot.
The beneficial effects of the present invention are: there are two one group of electricity of movable contact and two stationary contact disjunctions simultaneously for our switch tool
Road, therefore wherein break down for one group even if having, another set can also substitute work, therefore substantially increase of the invention steady
It is qualitative.Meanwhile the ability of two groups of contact breaking currents increases one times, the occasion for adapting to direct current electric power tools high current uses.
In addition we using the cooperation on-off of contact and conduction band control signal, often rubbed against between contact and conduction band, therefore contact surface
Oxidation will not be generated, the resistance for avoiding contact with face is excessive.In addition the addition of magnet, we can eliminate contact and disconnect moment generation
Electric arc.
