Through hole, described magnetic clasp lock include base, draw point, magnetic clasp and trip device, and described base is fixed on the bottom of experiment box cavity
Portion, its position is corresponding with the through hole on printed circuit board (PCB), and described draw point is fixed on base, and upwardly extends via through holes
Overhang to experimental box, described magnetic clasp is set in the top of draw point, and form lock with draw point is used for connection, described device of tripping
Magnetic clasp is unlocked, described toggle switch has multiple, is arranged on the surface towards experimental box side of printed circuit board (PCB), prints
Printed circuit board is provided with electronic circuit in another side surface, and the pin of toggle switch electrically connects with electronic circuit.
In a specific embodiment of the present utility model, described magnetic clasp is opened up for steel in centre and along short transverse
The endoporus of fastening by needle snap.
In another specific embodiment of the present utility model, described magnetic clasp has self-locking mechanism.
In another specific embodiment of the present utility model, the height of described experiment box cavity, printed circuit board (PCB)
Thickness and magnetic clasp endoporus height sum, be equal or slightly larger than the height of described draw point.
The utility model manually controls the closed and disconnected of each toggle switch point position, to the electronics on printed circuit board (PCB)
Circuit sets trip point and short dot, said structure compared with prior art, to have an advantageous effect in that：Toggle switch point digit
Amount can increase and decrease as needed, therefore can independent assortment go out it is various open circuit, short troubles, realize the recycling of printed circuit board (PCB),
Save cost；Toggle switch is locked in experimental box by magnetic clasp lock, and teacher opens experimental box to carry out failure by tripping device
Point is set, and student does not configure and trips device, can not open experimental box easily, thereby may be ensured that the disguise that failure is set；Dial
Code switch small volume, main body of the printed circuit board (PCB) as actual training device can be highlighted.
