The characteristics of the subminiature micro switch: small, small space, and very sensitive. Many high-tech products, especially electronic products, have micro switches. The micro switch also brought his characteristics to the extreme. Because of its small size, it has great effect. The matching manufacturers produced more beautiful products.
For example, the thinner and thinner ultra-thin mobile phones nowadays, it is precisely because of the existence of micro-switches that its appearance becomes more and more beautiful, and its volume becomes lighter and lighter.
1. Please do not use it under the condition of continuously applying vibration and shock to the small micro switch. The generation of abrasion dust may cause contact failures, malfunctions, and shortened life. In addition, if excessive vibration or shock is applied, the contact may malfunction, stick, or be damaged. Please install in a direction where resonance does not occur and where there is no vibration or impact.
2. Please do not use it in an environment with sulfide gas, ammonia, nitric acid, chlorine and other harmful gases and high temperature and humidity. Otherwise, malfunctions such as damage due to poor contact and corrosion of the contacts may occur.
1. On the fixation of the switch body
1). When fixing the main body of a small micro switch, please use M2 small screws to fix it on a smooth surface with a torque of 0.098N·m or less. In addition, to prevent the screws from loosening, it is recommended to use washers at the same time.
2). Please note that the action body should not directly exert force on the button or exciter in the free state, and exert force on the button in the vertical direction during use.
3). The operation setting after the operation is based on the O.T. value of 70[%] or more. In the case of a switch, do not set the operating body at the operating limit position, so as to avoid opening and closing and over-stroke caused by impact and shorten the life.
2. About the change of action characteristics
Regarding the change in the operating characteristics of the small micro switch, even if it changes within ±20[%] of the operating characteristic specification value, it should not cause malfunction.
3. Regarding welding operations
In the case of hand soldering, please use an electric temperature with temperature adjustment of 320℃max.) to complete the work within 3 seconds, and be careful not to apply force to the terminal during the work.
4. It is recommended to use low-power circuit type (Au-clad contact) when used under small current and voltage.
5, the environment
Do not use or store it in places where there is a bad influence on the contacts, corrosive gas, silicon, etc., or places with a lot of dust.
