Abstract
Provided is a double control power switch. The utility model mainly solves problems that an existing double control power switch has short service life and is easy to cause bad contact. The double control power switch is characterized in that an arched reed (10) is in a shape of round or oval. A positioning platen (11) is disposed on the arched reed (10). The positioning platen (11) is provided with a second press arm (7) which can pass through a groove (12). The double control power switch changes a shape of the reed and the positioning platen is added. The double control power switch is characterized by long service life, good contact effect and good feel of connecting and disconnecting.
Description
Technical field
The utility model relates to a kind of push-button switch, is specifically related to a kind of two control mains switch.
Background technology
Progress along with science and technology, for electrical automation, intelligent control development is very fast, as the washing machine in the household electrical appliance, microwave oven etc., generally all be to carry out program control by microprocessor, as to the time, temperature, operational mode, automatically stop to wait action to realize Based Intelligent Control, on control panel, generally all be provided with mains switch, because main working power is different with the operating voltage of control power supply, main working power adopts civil power, and (voltage is the 220V alternating current, be also referred to as forceful electric power), the control power supply is the direct current (being also referred to as light current) that is lower than 36V, and is compacter in order to make structure, occurs a kind of two control mains switch in the market, this two control mains switch is mainly by base, loam cake, push shaft (being button) and two pairs of pins are formed, push shaft below is provided with two by pressure arm, controls the connecting and disconnecting of the circuit that two pairs of pins are communicated with respectively, a pair of pin control forceful electric power wherein by pressure arm for two, when pressing push shaft, connect earlier, another controls light current to pin, and forceful electric power continues to press push shaft after connecting, and light current is connected.The pin of control forceful electric power is by the seesaw opening and closing, the pin of control light current is provided with U-shaped contact and bubble point contact, the bubble point contact is in-line and stretches to the center from the open side of U-shaped contact, and U-shaped contact and bubble point contact top are provided with one by the corresponding arch reed of pressure arm.There is following technological deficiency in this two control mains switch: 1, reed is rectangle, after repeatedly pressing, and elastic failure, useful life is short.2, the reed top does not have setting element, and main dependence is undertaken spacing by pressure arm, play easily takes place in use, causes loose contact maybe can't connect circuit.
The utility model content
In order to overcome existing two control mains switch short deficiency that easily causes loose contact that reaches in useful life, the utility model provides a kind of two control mains switch, this pair control mains switch has changed the shape of reed and has increased positioning pressuring plate, has long service life, contact is effective and the characteristics of the good hand touch of break-make.
The technical scheme that the utility model adopts is: a kind of two control mains switches, comprise base, loam cake, push shaft, first group of pin and second group of pin, push shaft below be provided with first by pressure arm and second by pressure arm, first to press pressure arm corresponding with seesaw, first by being provided with spring between pressure arm and the seesaw, first group of pin break-make of seesaw action control, second presses the corresponding arch reed in pressure arm below, second group of pin is that two and upper end are respectively equipped with U-shaped contact and bubble point contact, the arch reed is corresponding with U-shaped contact and bubble point contact, second group of pin break-make of arch reed action control, the arch reed is circular or oval, arch reed top is provided with positioning pressuring plate, and positioning pressuring plate is provided with second groove that can pass by pressure arm.
Described base below is provided with the alignment pin that matches with through hole on the circuit board.
Be provided with waterproof grommet between described loam cake and the push shaft.
The beneficial effects of the utility model are: owing to take technique scheme, improved the arch reed and kept flexible persistence, and then increased useful life, simultaneously, positioning pressuring plate can effectively be avoided arch reed play, the phenomenon that loose contact maybe can't be connected can not appear in use, and safe and reliable, when pressing push shaft, arch reed generation strain, second group of pin connected, and whether hand can be connected in perception during operation, and feel is preferably arranged.
