Resistance 4, insulation shell includes all to offer form on upper shell 1 and lower drain pan 2, upper shell 1 and lower drain pan 2, and upper shell 1 can be covered
On lower drain pan 2 so that viewing window position is overlapped to show the state of piezo-resistance；Lower drain pan 2 is vertical with form place side wall
Electrode through hole is offered respectively on two relative side walls, outside the two side walls, be also respectively provided with stopper slot, current bar
5th, arc piece 6 and spring 7；Current bar 5 adopts U-shaped laminated structure, and it is in one to be provided with an end of U-shape structure with this U-shaped
Determine the prolongation piece of angle, another end outwards extends vertically welding pin is formed, as outside L/N (fire/zero line) pin；Arc
Wedge-shaped indentation is provided with piece 6 as hitch structure, the size of wedge-shaped indentation is prolonged with the U-shaped laminated structure end of current bar 5
Lengthy motion picture size matches, and the inclination angle of wedge-shaped indentation is matched with piece angle is extended, the effect that current bar 5 can be driven to move；
One end of spring 7 is fixed on the end of stopper slot, and the other end connects arc piece 6, and arc piece 6 can be under the draw of spring 7
Move along stopper slot；Piezo-resistance 4 becomes an entirety by three voltage dependant parallel stackings, and its upper/lower electrode face connects gas jointly
