As shown in Fig. 3, Fig. 5 and Fig. 7, a thickening part 46 is formed on 4 the other end of the elastomer, the thickening part 46
It is arranged on first terminal 7, which folds from 4 end of elastomer to upper surface or lower face, or in elastomer 4
An elastomer block is superimposed on upper surface or lower face to form.By the thickening part 46 added in elastomer 4 (reed) one end, ensureing
Under the premise of whole feel, increases thickness, so that the wearability of elastomer 4 (reed) is improved, to improve the entirety of microswitch
Service life makes its service life reach 80,000,000 times in conjunction with the overall construction design of microswitch.
Microswitch provided in this embodiment for conducting with disconnection principle be:
Do not press lead core 3 when, elastomer 4 (reed) in the raw, i.e. the movable contact of elastomer 4 (reed) lower end
43 are in discrete state with the stationary contact 71 of 7 upper surface of first terminal, then first terminal 7 is off with Second terminal 8,
I.e. microswitch is off.
When downwards by core 3 is led, elastomer 4 (reed) is bent downward generation deformation by the downward active force of core 3 is led,
At this point, first encountering the pedestal glue platform 11 on pedestal 1 by the lower elastic strip 42 of elastomer 4 (reed), lower elastic strip 42 is set to occur soft
Property deformation the downward impact force of part is eliminated by the cushion effect generated, realize silencing function;Then, elastomer 4 (reed)
Continue downward, the movable contact 43 of elastomer 4 (reed) lower end is made to be contacted with the stationary contact 71 of 7 upper surface of first terminal, then first
Terminal 7 and Second terminal 8 are in the conduction state, i.e., microswitch is in the conduction state.
When discharging the pressing to leading core 3, is resetted upwards by the elastic restoring force of elastomer 4 (reed), make elastomer 4
The movable contact 43 of (reed) lower end is detached with the stationary contact 71 of 7 upper surface of first terminal, then first terminal 7 and 8 weight of Second terminal
New to restore to off-state, i.e. microswitch is off.
The above described is only a preferred embodiment of the present invention, be not intended to limit the scope of the present invention,
Therefore identical as the above embodiment of the present invention or approximate technical characteristic is used, and obtained other structures, the guarantor in the present invention
Within the scope of shield.
