In the above embodiment, the home appliance 300 is a washing machine.

Of course, the washing machine is not limited to a washing machine, and may be a wall-mounted washing machine, a clothes dryer, a washing and drying integrated machine, a microwave oven, an electric oven, an air conditioner, and the like.

The following is a detailed description of a washing machine as an example, and is compared with the prior art.

A plurality of micro-touch switches are arranged on a computer board of the existing washing machine and are used for controlling normal work of different programs. However, at present, the user classifies the clothes more and more carefully, and the requirement on the clothes program of the washing machine is also increased synchronously, so that the whole computer board layout is more and more compact, and even the phenomenon of insufficient layout space occurs on the small kilogram washing machine.

At present, a power switch is welded on a PCB and cannot be structurally separated, so that the workbench and a computer board are easily dislocated or have large gaps during assembly. Meanwhile, the working environment of the PCB of the washing machine is wet, and the PCB needs to be completely filled with glue and be waterproof, so that the replacement cost of the power switch after sale is very expensive. In addition, the existing power switch welded on the PCB uses a micro-touch switch, the power switch has no pause feeling when the button is pressed or bounced, and a user cannot feel the rhythm feeling when the button is pressed and cannot meet the sensory requirements of the user.

As shown in fig. 1, the present specific example provides a power switch, which includes a button cap, a switch upper cover, a switch base, a switch member, and an outgoing line.

Step 2: the two ends of the upper cover of the power switch are clamped on the base.

And step 3: the power switch is assembled to the table by screws.

The working principle of this specific example is: the power switch is independently connected with the computer board of the whole machine through the outer lead, and the power switch is sealed by the switch upper cover and the switch base which are matched in a clamping manner and then is in threaded connection with the workbench of the whole machine. Simultaneously, increase mistake proofing pencil and pass through the groove, when guaranteeing the mounted position of switch spare on switch base, improved foolproof nature and structural consistency greatly, make switch and base joint firm simultaneously, need not the point and glue simple to operate. The outer lead root of the power switch is subjected to dispensing treatment, so that the waterproofness and the safety of the power switch are improved.

The smooth button cap on the top surface is added on the switch upper cover, so that the operation comfort of the power switch is improved, and the problem that the existing button is easy to wear is solved. This design switch is inside to adopt about reed structure for button cap presses down or produces momentary pause and frustrate sense and clear and crisp sound when bouncing, has promoted user's operation experience and has felt.

The button cap and the switch upper cover are made into an integral body, and the button cap and the switch base adopt an occlusion type clamping structure. Because the power switch is often acted by external pressure, the top of the power switch is easy to damage, and the switch identification pattern is easy to wear off. This design is independent from the workstation with switch to come out alone with the switch sign from whole picture and text paster, the top of protection switch spare that the button cap can be fine, and can change after the button cap is used for a long time, prolonged the life of switch spare, reduce after-sales cost of maintenance of after-sales user.

In addition, after the power switch is separated from the PCB, the layout of the display screen of the workbench can be improved. The power switch can be arranged at any position of the workbench along with the effect diagram, is not limited by the layout of PCB hardware any more, and beautifies the appearance of the whole machine.

Furthermore, the scheme can be used in the field of household appliances, beautifies the appearance of the workbench, improves the installation structure of the conventional power switch, and reduces the market reject ratio and the after-sale maintenance cost.
