In off-state；When the front of the scale body is placed with weight, switch positive pole part and switch the anode member contact,
The control circuit forms closed circuit.
The unlocked part for being arranged on the scale body reverse side includes in switch positive pole part and the switch anode member
Bottom plate and electric contact piece, the electric contact piece are fixedly installed on the bottom plate, and are reversely higher by towards the scale body described
Bottom plate, when the scale body front place weight when, the bottom plate can relatively described electric contact piece it is reverse towards the scale body
Motion.
Connected between the electric contact piece and the bottom plate using helical structure.
Connected between the electric contact piece and the bottom plate using fulcrum structure.
Relative to prior art, the present invention has the following advantages：
(1) front of scale body is used for bearing weight, and pressure switch is arranged on the reverse side of scale body, weight can directly,
Equably transfer the pressure in pressure switch so that accurate, the uniform stress of pressure switch energy, so as to improve electronic induction scale
Weighing accuracy rate.
(2) using the reverse side that scale body is symmetrically distributed in after multiple pressure switch parallel connections, can more uniformly, accurately by
Power, and when the failure of which part pressure switch is unable to stress, other pressure switch stress are not influenceed, so as to not influence
The use of electronic induction scale.
(3) pressure switch is divided into positive pole part and anode member, card dismantling connection between positive pole part and anode member, convenient
Change the positive pole part or anode member on unlocked setting scale body.
(4) unlocked the positive pole part being arranged on scale body or anode member are simple in construction, cost is low, and can rise
Acted on to electronic induction scale feet, using fulcrum structure or helical structure so that relative motion is held between electric contact piece and bottom plate
Easily realize, be advantageous to disconnection and the closure of control circuit.
