Description

Technical Field

[0001] The utility model relates to the technical field of angle grinder switches, in particular to a reinforced dustproof switch. Background Art

[0002] Angle grinder, also known as grinding machine or disc grinder, is a kind of grinding tool used for cutting and grinding fiberglass. There is often a risk of accidental touch during the use of angle grinder. Therefore, an angle grinder switch must be installed on the angle grinder. The angle grinder switch is a tool accessory that is easy to operate, safe and reliable. It can not only greatly improve work efficiency, but also improve work safety. However, the current angle grinder switch still has the following shortcomings:

[0003] For example, the patent document with application number 202321804295.9 discloses a signal switch for an angle grinder. The signal switch for the angle grinder can rub off the oxide layer on the conductive contact piece through brush sliding, which plays a self-cleaning function, making the circuit connection reliable and ensuring the output of the electrical signal. In addition, the brush-type sliding contact has reliable contact and better vibration resistance, short arcing time, and extended service life of the switch. However, after long-term use, due to the intrusion of a large amount of dust, the contacts are worn and the internal active parts are stuck, causing the switch to fail.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a reinforced dustproof switch is proposed. Utility Model Content
