Below by drawings and examples, the technical solution of the utility model is described in further detail.
It is a kind of power cord with switch as shown in Figure 1, Figure 2 and Figure 3, including：Attaching plug 1, the first power cord 2,
Control switch 3, second source line 4 and plug 5.
Control switch 3 is provided between the attaching plug 1 and plug 5, which can be according to electricity consumption
Circuit is turned off or is closed by demand, especially when people do not need electricity consumption, only need to utilize control switch 3 that circuit breaks
It opens, is in electroless state, improves the safety of product；First power cord 2 is located at attaching plug 1 and control switch 3
Between, the second source line 4 is located between control switch 3 and plug 5.The both ends power line structure is identical.And
The power cord is made of three identical cores 18 and two insulating barriers 19.Outside three identical cores 18
It is enclosed with insulating layer 20, three identical cores 18 for being enclosed with insulating layer 20 are wrapped with anti-magnetosphere 21, described
Two insulating barriers 19 be spaced one from three identical cores 18, three identical cores 18 for being enclosed with anti-magnetosphere 21
It is enclosed with braiding layer 22 with outside two insulating barriers 19, the braiding layer 22 is wrapped with wearing layer 23.The insulating layer 20,
Cavity 24 is formed between anti-magnetosphere 21 and insulation board 19, and cotton yarn is filled in the cavity 24.
The control switch 3 includes：Shell 41, movable contact piece 43, lock chamber 44, latch fitting 45, presses 46 and of press button at stationary contact part 42
