Abstract
The utility model belongs to the electric appliance field, relates to an electric appliance switch, especially an up-hung type switch drop-off prevention apparatus. The up-hung type switch drop-off prevention apparatus comprises an upper contact piece and a movable lower contact piece; and is characterized in that: the upper contact piece has a positioning pin on its upper portion; the positioning pin is passed through the upper contact piece, has an inside spring and a pulling part on the top; the lower contact piece has a groove to limit the positioning pin. In this way, the up-hung type switch drop-off prevention apparatus of the utility model can enable the upper contact piece and the lower contact piece of an electric appliance switch to contact tightly; and achieves the advantages of drop-off prevention and safe using.
Description
Technical field
The utility model relates to appliance field, relates to appliance switch, particularly a kind of upper hanging type switch anti-drop device.
Background technology
In the prior art, the upper hanging type switch has last contact and movable following contact, last contact relies on that identical gap extruding contacts with following contact and it is come off, the such switch of long-time use, the phenomenon that loose contact will occur, having under the situation of wind in addition, it is come off, thereby influencing the normal use of switch.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned shortcoming, provides under a kind of last contact that can make switch the contact contact closely, the upper hanging type switch anti-drop device that can not come off.
The technical solution of the utility model is achieved in that upper hanging type switch anti-drop device, comprise contact and movable following contact, it is characterized in that: the described contact top of going up has alignment pin, and alignment pin passes contact, its inside has spring, and top has the nose of drawing; Following contact has the groove of having jurisdiction over the alignment pin bottom.
The beneficial effects of the utility model are: such upper hanging type switch anti-drop device have can make that contact on the appliance switch and movable following contact contact closely, can not come off advantage, use safer.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein: 1, go up contact 2, down contact 3, alignment pin 4, spring 5, draw nose 6, groove
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, upper hanging type switch anti-drop device comprises contact 1 and movable following contact 2, it is characterized in that: described contact 1 top of going up has alignment pin 3, and alignment pin 3 passes contact 1, and its inside has spring 4, and top has the nose of drawing 5; Following contact 2 has the groove 6 of having jurisdiction over the alignment pin bottom.
