12 pressure value N are L2/（L1+L2）× F, thus avoids mechanical dead point in sound contact（That is the Y of fulcrum two）So that
Reliability when there is the contact pressure of abundance the moment that switching circuitry is connected to ensure that switch is powered.Same operation principle,
Release be applied to after the operating physical force on plunger 3, by compression F springs 2 screen resilience effect under, plunger 3 drive depression bar assembly to
Move left, the Lb of C reeds 7 part is produced elastic potential energy by compression, in depression bar 8 to the left across after the Y of fulcrum two, the bullet of C reeds 7
Property potential energy is changed into the kinetic energy of movable contact spring 11, it is quickly overturn, so that moving contact 13 is separated with static contact 13 from contact condition
To being fully disconnected（Refer to the minimum space distance for reaching breaking arc）The required time accelerates to arrive several milliseconds.
Fig. 9-10 is movable contact spring modular construction schematic diagram, and the F reeds 9 that high-yield strength material makes are stuck on terminal 10,
The frame of movable contact spring 11 is on terminal 10, while F reeds 9 are pressed at two arc convex of movable contact spring 11, the central shaft of arc convex
The central axis coaxial that line rotates with movable contact spring 11 around terminal 10, in the rotary course of movable contact spring 11, by the pressure of F reeds 9
F1, F2 are constant, in the presence of this pressure, and it is operationally that inversion or side are put and may insure terminal 10 no matter to switch
Can reliably it be contacted between movable contact spring 11；The F reeds 9 are jump ring.The movable contact spring 11 is pressed in terminal 10 by F reeds 9
On, reliable contacts discharge off between the upset moment of movable contact spring 11 and terminal 10, what solution movable contact spring 11 departed from from terminal 10 asks
Topic；
Such as Figure 11-12, the static contact component is split modular structure, and elastic construction can absorb the impulsive force for connecting moment,
Prevent spring from producing the adhesion that electric arc is caused.The static contact 2 14 is, by relatively thin high conductivity copper alloy making, to realize low
Conductive capability is improved while coefficient of elasticity, mitigates temperature rising degree when high current is powered；The static contact 2 14 is used
Riveting or welding manner are reliably fixed on static contact 1, and both constitute one；Being riveted simultaneously on static contact 2 14 has
Static contact 13, for increase riveting intensity and heat dispersion, the riveting position of static contact 2 14 and static contact 13 is in 180 ° of reflexeds,
Reach double thickness；
In switch connection, movable contact spring 11 is overturn, moving contact 12 hit static contact 13, static contact 2 14 withstand shocks power when produce
The deformation of certain amplitude, makes static contact 13 be close to moving contact 12 and makees experiencing small oscillating movements, mitigate spring and cause moving contact 12 and stationary contact
Electric arc between first 13, prevents two contacts from adhering；Figure 13 is that static contact component is encased in the schematic diagram after shell 16, and thick dashed line is tactile
The flow path signal of electrode current when head is just closed；
The static contact component is dual conducting structure, in addition to flexible terminal constitutes galvanic circle, static contact 13 and stationary contact
Piece 1 directly contacts the other galvanic circle of composition, it is ensured that reliability when high current is persistently powered；Figure 14 is shown out
Fully switched on state is closed, the upper right side of static contact 1 is provided with boss, and boss is located at the lower section of static contact 13, switched from connection
Moment is persistently mobile during being pressed into bottom to plunger 3, what the pressure for being applied to movable contact spring 11 in depression bar 8 was basically unchanged
Under the premise of, depression bar 8 is moved from Figure 13 close to the Y of fulcrum two position at moving contact 12, the arm of force of depression bar 8 and the fulcrum two of terminal 10
Become larger, pressure component can gradually increase between moving contact 12 and static contact 13, cause static contact 2 14 to be deformed, most
Force to contact at G points with the boss of static contact 1 in the bottom of whole static contact 13.
Exemplified by as shown in Figure 14, the power suffered by static contact 13 has three below：A：Come from the downward power of moving contact 12；
B：Come from the upward power of static contact 2 14；C：Come from the upward power of static contact 1.Its relativeness is A=B+C, stationary contact
The coefficient of elasticity design load of piece 2 14 is relatively low, and B force value is set as less than the 1/2 of A, has between static contact 13 and static contact 1 and fills
The contact pressure of foot makes its contact reliably, and caloric value is low during energization；The flow path of electrode current when thick dashed line is contact closure,
Dual conducting is constituted between movable contact spring 11 and static contact 1, line resistance is reduced；Turn on the C1 of loop one：Movable contact spring 11 → dynamic tactile
2 14 → static contact of first 12 → static contact, 13 → static contact 1；Turn on the C2 of loop two：Movable contact spring 11 → moving contact, 12 → stationary contact
First 13 → static contact 1.
The D.C. high-current appliance switch is reasonable in design, compact conformation, utilizes the depression bar that can be swung by designated magnitude
Component, mechanical dead point is eliminated while lifting movable contact spring reversal rate；Movable contact spring is buckled on terminal with reed, is begun between the two
Contact is forced eventually, even in same reliable contacts between upset moment movable contact spring and terminal；Static contact component is split-type structural,
Flexible terminal structure absorbable connection moment comes from the impulsive force of moving contact, prevents spring from producing electric arc and causing viscous
；Static contact component is dual conducting structure, in addition to flexible terminal constitutes galvanic circle, and contact constitutes conductive return again up and down
Road, it is ensured that reliability when high current is persistently powered.
, it is necessary to illustrate in the description of this D.C. high-current appliance switch, unless otherwise clearly defined and limited,
Term " setting ", " connected " and " connection " should be interpreted broadly, for example, it may be fixedly connected or be detachably connected,
