Description

A kind of sensitive switch

Technical field

The utility model relates to field of switches, relates in particular to a kind of sensitive switch.

Background technology

Sensitive switch is the very little sensitive electronic component of a kind of volume, and it is of many uses, and model is various, the sensitive switch of every kind of model can by or the electric current difference of bearing, it uses frequent, when electric current is big silver layer on the five metals parts is caused fusion, and its reliability life-span is lower; Various being difficult to of model recognized; Its housing is injection molded, and technology is complicated, and material cost is also high.

The utility model content

The problem that the utility model solves is the defective that existing sensitive switch cost height, model are difficult to recognize, the reliability life-span is lower, and a kind of sensitive switch is provided, and the cost of material is low for it, the life-span long, easily identification.

The utility model embodiment provides a kind of sensitive switch, comprise housing, actuating mechanism, and part places the button in the described housing, described actuating mechanism comprises the first terminal, second terminal, the 3rd terminal and shell fragment mechanism, described the first terminal one side is provided with first fixed contact, described second terminal, one side is provided with second fixed contact relative with the described first fixed contact position, described shell fragment mechanism is provided with the moving contact between described first fixed contact and second fixed contact, described housing comprises upper cover body and lower cover, in described upper cover body one side terminal groove and touch pole groove are set, a side relative with described touch pole groove place side is provided with two grooves spaced apart from each other, and described lower cover covers with described upper cover body and is connected; Have 10 silver coating on described first fixed contact, second fixed contact and the moving contact, have 10 silver coating on the described the first terminal; Described button top arranges a touch pole movable up and down, and described touch pole one end is arranged in the described housing; Described the first terminal and the bending of second terminal middle part.

Sensitive switch described in the utility model, beneficial effect is:

Upper cover body and the lower cover internal structure of housing are simplified, reduced moulding process, and then reduced material cost, the shell structure of producing is simple, easy-to-use; The silver layer of each contact is selected suitable thickness, in use can increase the reliability life-span of switch integral body.

Embodiment

For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model is described in further detail.

Embodiment 1:

Sensitive switch described in the utility model, shown in accompanying

drawing

3,4, it comprises that housing 1, housing 1 comprise upper cover body 11 and lower cover 12.

Shown in accompanying

drawing

7,8, in described upper cover body 11 1 sides terminal groove 15 and rocking bar groove 16 are set, a side relative with described rocking bar groove 16 place sides is provided with two grooves 17 spaced apart from each other, and described lower cover 12 covers with described upper cover body 11 and is connected.

As shown in Figure 1, it also comprises actuating mechanism 2, touch structure 2 comprises the first terminal 4, second terminal 5, the 3rd terminal 6 and shell fragment mechanism 7, the first terminal 4, second terminal 5, the 3rd terminal 6 all part is arranged in the housing 1, the first terminal 4 one sides are provided with first fixed contact 8, second terminal, 5 one sides are provided with second fixed contact 9, first fixed contact 8 is relative with second fixed contact, 9 positions, shell fragment mechanism 7 is provided with moving contact 10, moving contact 10 is arranged between first fixed contact 8 and second fixed contact 9, its can with first fixed contact 8, second fixed contact 9 contacts respectively.Be provided with circular or oval-shaped terminal hole 18 on the first terminal 4, second terminal 5 and the 3rd terminal 6.The first terminal and the bending of second terminal, 5 middle parts.
