Background technology
Microswitch is that have small contact separation and snap-action mechanism, and it is dynamic to carry out switch with defined stroke and defined power
The contact mechanism of work, because the contact spacing of its switch is smaller, therefore named microswitch is called sensitive switch.
Currently, the Chinese patent document that Authorization Notice No. is CN202384225U in the prior art disclose it is a kind of dust-proof micro-
Dynamic switch, including shell and its interior tension spring, movable contact spring, stationary contact, movable contact, tension spring are set on holder and by by keying
System, tension spring are connect with movable contact spring, and normally closed terminal and normally opened terminal inner end are respectively arranged with and contact or divide with movable contact on movable contact spring
From stationary contact, compressing tension spring is moved down by button, tension spring drives movable contact spring, the movable contact on movable contact spring and normally open end
The stationary contact point contact conducting of son, after the downward force of button disappears, tension spring resets, the movable contact on movable contact spring just with normally closed terminal
Stationary contact point contact.The outer end of holder, normally closed terminal and normally opened terminal extends respectively to form connecting terminal, and terminals outside shell
Son with shell through hole junction fill out envelope marine glue to prevent dust granules from entering in shell, switch through glue be honored as a queen surface U.S.
It sees, the defects of no leak adhesive, glue is dry, poor bonding strength.
But sealing is formed by filling out envelope marine glue in connecting terminal and shell through hole junction, it not only needs to filling out
The marine glue dosage of envelope is controlled, and microswitch is placed a period of time waiting marine glue and solidified by intermediate demand, in waterproof
If the connecting terminal filled out before gelling is solid at envelope marine glue is bent, the close condition effect of marine glue, Er Qiefang are not only influenced
The deformation of connecting terminal also is difficult to restore after glue solidification, influences to use.
