Description
Technical field
The utility model relates to a kind of sensitive switch.
Background technology
Sensitive switch is to have small contact separation and fast actuation mechanism, the contact mechanism that carries out the moving action of switch by the stroke of regulation and the power of regulation, cover with shell, there is a kind of switch of drive rod its outside, because the contact spacing of its switch is smaller, therefore named sensitive switch, is again sensitive switch, and at present its sensitivity of sensitive switch is on the market not high, conversion speed is also inadequate.
Summary of the invention
The purpose of this utility model is to overcome the defect of prior art, and a kind of compact conformation, the sensitive switch that highly sensitive, conversion speed is fast are provided.
For achieving the above object, the utility model adopts a kind of sensitive switch, comprise base, upper cover, with the first terminal being arranged in upper cover, the second terminal, the 3rd terminal, can moving plate, switch and spring, described base is formed with an installation cavity, the first terminal, the second terminal and the 3rd terminal adaptation are arranged in the installation cavity of base, the contact jaw of the first terminal and the second terminal is corresponding and be provided with contact, described the 3rd terminal is arranged on a side of base, described spring connection is arranged on the 3rd terminal, switch is arranged on base upper end and one end is pressed on spring, described one end that can moving plate is arranged in the fluting of the 3rd terminal, the other end that can moving plate is arranged between the first terminal and the contact of the second terminal, the other end of described spring forms and is connected with mid portion that can moving plate, described one end can moving plate being arranged in the 3rd terminal fluting is provided with vertical chamfering.
The utility model further arranges again, described left end that can moving plate forms symmetrical two parts installation end, be provided with vertical chamfering at the top of each installation end, right-hand member upper/lower terminal face that can moving plate is provided with contact, respectively the contact jaw contact setting of corresponding the first terminal and the second terminal.
In sum, the beneficial effects of the utility model are: after improvement, and this microswitch structure novelty, in order to improve the sensitivity of NL sensitive switch, conversion speed, to can changing by moving plate of switch; Make vertical chamfering into from traditional inclination wedge angle, few with the 3rd terminal fluting contact-making surface like this, thus promote the conversion performance of switch.
