Embodiment Construction
[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0018] Such as Figure 1~4 Shown is a preferred embodiment of the present invention.
[0019] A mechanical switch with a button state indication function, comprising a housing 1 and a key switch 2 installed on the housing 1, the key part 21 of the key switch moves through the front end of the housing 1, and the key switch 2 adopts a spring structure The self-locking mechanical push switch, when the key switch 2 is pressed, the power on the switch is turned on, and the switch is in the open state. It is a conventional mechanical switch structure and is widely used in various control switches on the front surface of the range hood. This key switch can realize multiple different functions, such as controlling the switch of the lighting lamp on the range hood, the size switch of the wind speed, the main power switch, etc. This key switch generall...

The invention relates to a mechanical switch with a key status indication function. The mechanical switch with the key status indication function comprises a shell and key switches arranged on the shell, and is characterized in that the front end face of the shell is provided with observation windows; indication blocks capable of vertically sliding are arranged in the shell; each indication block is provided with an indication part used for displaying the corresponding switch status; the shaft of each key switch and the corresponding indication block are movably connected by a linkage structure; each key switch is pressed to an on position, each indication block is driven to move up by the corresponding linkage structure, and each indication part is over against the corresponding observation window; each key switch is pressed to an off status, each indication block is driven to move down by the corresponding linkage structure, and each indication part is over against the corresponding observation window. An operator can visually know the working status of each key switch by whether the indication parts can be seen from the observation windows, the switch statuses are reliably displayed, and the indication function is realized. The mechanical switch with the key status indication function is of a pure mechanical structure. Compared with a switch realizing the indication function by an electronic mode, the mechanical switch with the key status indication function is simpler in structure, low in cost, can be used for a long time in a complex environment and is stronger in practicability.
Description
technical field [0001] The invention relates to a mechanical key switch, in particular to a mechanical switch with a key state indication function, which is especially suitable as a control switch in front of a range hood. Background technique [0002] The key switches commonly used in daily life are mechanical and electronic. Ordinary mechanical key switches are directly connected to the mains and have the advantages of simplicity, reliability, and low cost, but generally do not have a display function. After pressing the switch, you can only observe whether the switch is pressed through the depression of the button. The indication is not obvious. Use Lack of humanity. Generally, key switches with a display part are mostly electronic switches, and electronic switches are widely used to control machinery and equipment. They appear in different applications, such as transfer switches, key switches or emergency stop switches. The command device of the electronic switch is as...
