Abstract
A microswitch relates to the technical field of switches and comprises a base and a switch cover shielded at the upper end of the base, wherein the switch cover and the base form a cavity fixed with an insert therein; a reed is connected with and arranged at the upper end of the insert; a contact is arranged at one end of the reed; and a button is arranged at the upper end of the switch cover. The microswitch has the advantages of simple structure, reasonable design, strong restoring force and long service life, and can reach 12 million times of error-free operations in a normal environment.
Description
Technical field:
The utility model relates to the switching technique field, relates in particular to a kind of sensitive switch.
Background technology:
Switch is the element of make-and-break contact, and also has the initiatively function of preventing electric fire.Switch application is at various electronic equipments, in the household electrical appliance.Sensitive switch is a kind of quick converting switch of exerting pressure and actuating, because the contact spacing of its switch is smaller, therefore named sensitive switch is again sensitive switch.
Sensitive switch is controlled in the equipment of the frequent changing-over circuit of need and safeguard protection etc. automatically; be widely used in electronic equipment, instrument and meter, mine, electric power system, household electrical appliance, electric equipment; and the military field such as space flight, aviation, naval vessel, guided missile, tank; though sensitive switch is little, play irreplaceable effect.
In the prior art, sensitive switch is owing to the defective on design and the production technology, and the restoring force of switch is not strong, can not satisfy high frequency and use needs, and useful life is short.
The utility model content:
Technical problem to be solved in the utility model is to overcome the defective of prior art, provides that a kind of restoring force is strong, the sensitive switch of long service life.
Technical problem to be solved in the utility model realizes by the following technical solutions.
A kind of sensitive switch, it is characterized in that: comprise pedestal and the switch cover that covers on the pedestal upper end, be fixed with inserts in the cavity that switch cover and pedestal consist of, described inserts upper end arranges reed and connects, described reed one end arranges the contact, and described switch cover upper end arranges button.
Described contact is silver point.
Described button lower end contacts with reed.
The utility model is simple in structure, reasonable in design, and restoring force is strong, can reach 1,200 ten thousand times normal running under home, long service life.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of sensitive switch comprises pedestal 1 and the switch cover 5 that covers on pedestal 1 upper end, be fixed with inserts 3 in the cavity that switch cover 5 and pedestal 1 consist of, described inserts 3 upper ends arrange reed 4 and connect, and described reed 4 one ends arrange contact 2, and described switch cover 5 upper ends arrange button 6.
Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
