Construction of switch described in the utility model, the lower end of seesaw is provided with moving contact, and following copper sheet is provided with equally near the seesaw end and is used for the fixed contact that contacts with the seesaw moving contact.Described rocker assembly is T-shaped, is used to connect pressing board and seesaw.Rocker assembly comprises a fixture block that is stuck in the pressing board inboard by back-off, the fixture block medial surface is vertically installed with and is empty tubbiness spring housing in the middle of one, in adorn a spring, be inserted with in the spring and connect contact with seesaw top always, the top elasticity of spring of can utilizing in spring housing is freely stretched under external force.
Described construction of switch, the contact position of last copper sheet and seesaw are convex shape, and seesaw utilizes the effect of top power to form movable tight the contact with last copper sheet raised position, and seesaw can be the form action of center with seesaw with the salient position according to top position.Above salient position the time, the perk of seesaw movable contact head end makes moving contact contact with following copper sheet fixed contact when top, and copper sheet and following copper sheet conducts in the realization.Simultaneously, in last copper sheet and following copper sheet installation place, be provided with the rigidity buckle that is used to be connected external cable respectively with last copper sheet and following copper sheet contact, be provided with the wire guide that is used for the external cable access in back seat back and rigidity buckle correspondence position, after only the insulation rubber of electric wire outside need being cut away, metal is partly inserted, and the rigidity buckle can block electric wire in the other direction, realizes fast-wiring.
Construction of switch described in the utility model, following copper sheet can be provided with two, and seesaw can be contacted with two following copper sheets respectively under two kinds of location statuss, realizes the function of two controls of switch.
Construction of switch described in the utility model, the method for utilizing seesaw form and moving contact to contact with fixed contact realizes quick break-make, space hold is little, the stock utilization height, the rigidity buckle can carry out external cabling fast.Simultaneously, can set up a copper sheet that is used for external connection, make switch have the function of two controls.
Description of drawings
Accompanying drawing 2 is the utility model structural representation during as a double control switch.
Embodiment
For the ease of understanding, structure of the present utility model and operating principle are further described in detail below in conjunction with accompanying drawing:
As Fig. 1 is the utility model structural representation during as a single-pole switch, this construction of switch mainly partly is made up of housing parts and internal structure, housing parts comprises a back seat 1, one is installed in the protecgulum 2 and a pressing board 3 that is used for the control switch folding in back seat 1 front, and the internal structure part mainly comprises a power supply changeover module that is installed in the rocker assembly on the pressing board 3 and is used to control on/off.
