Problems solved by technology

[0002] For high-current inductive loads, electric tool loads and capacitive loads that use rocker switches as power switches, because inductive loads and electric tool loads will generate an inrush current about 6 times the rated current when starting, and capacitive The load has a discharge impulse current (the impulse current is related to the capacitor capacity and is proportional), resulting in arcing and high temperature; when the instantaneous current is large, the switch dynamic point and static point will be sintered together, so that the switch cannot work normally. After the external power supply is turned off, the switch can work again after the internal temperature of the switch drops, but the silver point sintering phenomenon will still occur during the follow-up work

Embodiment 1

[0026] A new type of forced disconnection rocker switch, its structure is as follows figure 1 As shown, it includes a button part 1, a compression spring 2, a movable contact part 3 and a housing part 4, the button part 1 is arranged on the upper part of the housing part 4, the compression spring 2 is arranged on the lower part of the button part 1, and the movable contact part 3 is connected to At the bottom of the compression spring 2.

[0027] The button component 1 includes a button cover 11 and a button seat 12 , the button seat 12 is installed in the button cover 11 , a downward boss is arranged on the button seat 12 , and the compression spring 2 is clipped on the boss. The button cover 11 can be in a planar shape, a V-shaped shape, a curved surface shape, a dot light curved surface shape or a waterproof curved surface shape. Light emitter 13 can also be set in button cover 11, and the structure of button part 1 is as follows: Figure 2-3 shown, where figure 2 does ...

Embodiment 2

[0030] A new type of forced disconnection rocker switch, most of its structure is the same as that of Embodiment 1, and the shell components used are such as Figure 5 As shown, it is a single-pole-single-throw structure, including a housing 41, a side contact pin 43, a static contact 42 and a middle contact pin 44, the static contact 42 is in contact with the movable contact 32, The middle contact pin 44 is arranged in the middle of the bottom surface of the shell 41, the side contact pin 43 is set on one side of the middle contact pin 44, and the shell 41 is provided with a resistance spring 46 and a resistor 47, and the resistor 47 is set on one side of the movable contact piece 3 , The resistance spring 46 is clamped on the resistance 47.

Embodiment 3

[0032] A new type of forced disconnection rocker switch, most of its structure is the same as that of Embodiment 1, and the shell components used are such as Image 6 As shown, it is a single-pole double-throw structure, and the structure of the double-throw movable contact is as follows Figure 8 shown. The shell assembly includes a shell 41, 2 side contact pins 43, 2 static contacts 42 and 1 middle contact pin 44. The two static contacts 42 are arranged on both sides of the movable contact 32 and are connected in contact with the movable contact 32. , The middle contact pin 44 is arranged in the middle of the bottom surface of the shell 41, and the two side contact feet 43 are respectively arranged on both sides of the middle contact pin 44.

Abstract

The invention relates to a novel rocker switch capable of being forcibly disconnected, which comprises a push button part, a compression spring, a movable contact spring part and a shell part, wherein the push button part is arranged at the upper part of the shell part, the compression spring is arranged at the lower part of the push button part and the movable contact spring part is connected with the bottom of the compression spring. Compared with the prior art, the novel rocker switch capable of being forcibly disconnected has the advantages the application scope is wide, the problem that the switch cannot be disconnected because sliver points are sintered can be thoroughly solved, the switch is enabled to work normally, the safety and the reliability are high, and equipment faults and safety accidents caused by combination of contacts can be effectively avoided through forced disconnection.

Description

technical field [0001] The invention relates to a rocker switch, in particular to a novel forced disconnection rocker switch. Background technique [0002] For high-current inductive loads, electric tool loads and capacitive loads that use rocker switches as power switches, because inductive loads and electric tool loads will generate an inrush current about 6 times the rated current when starting, and capacitive The load has a discharge impact current (the impact current is related to the capacitance, which is proportional), resulting in arcing and high temperature; when the instantaneous current is large, there will be a phenomenon that the switch dynamic point and static point are sintered together, so that the switch cannot work normally. After the external power supply is turned off, the switch can work again after the internal temperature of the switch drops, but the silver point sintering phenomenon will still appear during the follow-up work.
