Description
Technical field
The utility model relates to a kind of appliance switch.
Background technology
At present, all kinds of appliance switches are in its operating process, the phenomenon that generally all has the electric spark flicker when contact on the switch movable contact spring 3 and switch contact 4 separate, this phenomenon are commonly referred to the switch sparking, are the cutaway view of ordinary appliances switch shown in the accompanying drawing 1, wherein 1 is switch case, 2 is switch key, and 21 is the switch column cap, and 22 is spring, 3 is the switch movable contact spring, and 4 is switch contact.The existence of this phenomenon has influenced the confidence level of user to the appliance switch fail safe greatly, and simultaneously, the switch sparking that exposes also has some potential potential safety hazards really.At this drawback, common improvement project is to change better appliance contact and the contact of performance, as use silver or platinum etc. as contact and contact material, perhaps on contact and contact, smear various arc extinguishing greases, but these improvement projects make all the production cost of appliance switch improve greatly.
The utility model content
The purpose of this utility model be to provide a kind of simple and reasonable, cost of manufacture is low, can avoid exposing the appliance switch of electric spark, to overcome weak point of the prior art.
A kind of appliance switch by this purpose design, comprise the switch key that is arranged on the housing, also be provided with switch movable contact spring and switch contact in the housing, switch key and movable contact spring join, its architectural feature is to be provided with light barrier in the housing, light barrier is arranged on the side that contact is closed in the built-in relieving of housing, and the part lid of its outstanding inner walls is pressed in the switch contact top.
Above-mentioned light barrier is the L font, and the one end side surface is pasted mutually with inner walls, and its other end extends to the housing middle part, and lid is pressed in the switch contact top.Light barrier one end middle part is provided with open slot, open slot end at one end be provided with the wedge shape pin, this end side surface is provided with the profile of tooth insert edge.
Above-mentioned light barrier is chevron shaped, the one end side surface is pasted mutually with inner walls, and its other end is the arc limit, and this arc limit is provided with open slot, switch movable contact spring middle part slidably is arranged in this open slot, and the head that the switch movable contact spring contacts with switch contact partly covers and is pressed in below, arc limit.The end on light barrier arc limit is resisted against the housing base portion.
Above-mentioned light barrier and housing are integrated.The back-moving spring that switch key one side and is arranged in the housing joins.Switch key joins by column cap and movable contact spring, is provided with spring in the column cap.
The utility model is provided with light barrier on the basis of ordinary appliances switch, the electric spark that produces because of the open and close appliance switch will be closed or be limited in a certain zone in the switch case, avoid it to expose.
The utility model is applicable to the appliance switch of various structures, and the appliance switch of charged source indicator light or not charged source indicator light also can be suitable for, and switch column cap wherein can use ball, copper sheathing or protruding ball to replace, and does not influence its actual effect.
The utility model is simple and reasonable, cost of manufacture is low, can avoid exposing electric spark, and effect is remarkable.
