at work, everyone often talks about function keys. in many cases, waterproof micro switch. the waterproof micro switch is a kind of switch with fine contact spacing and quick-action organization, which uses the required stroke arrangement and required force to carry out the switching action. it is covered by a casing and has a push rod outside. the contact points are relatively small, so it is called a micro switch, also called a sensitive switch.
do you know a lot about the application precautions of waterproof micro switch during the whole application process?
1. when fixing the main body of the switch, please use small m3 screws to fix it on a smooth surface with a torque within 0.098n·m. in addition, in order to avoid loosening of the screws, it is recommended to apply a sealing ring at the same time.
2. it must be noted that the action body cannot immediately add energy to the button or the exciter under random circumstances, and the energy should be increased in the vertical angle for the button during application.
3. the action setting after the action is based on more than 70% of the o.t. value. in the case of a switch, do not set the action body on the position of the action level, to prevent the impact of the opening and closing, and the over-travel arrangement to reduce the service life.
4. regarding the change of operating characteristics, even if there is a change of ±20% of the operating characteristic specification model value, it should not cause common faults.
5. in the case of manual electric welding, please use automatic welding equipment with temperature adjustment (the highest value is 320℃), and work within three seconds, and pay attention not to increase energy on the terminal part during work.
6. when used under small current intensity, it is recommended to use a small output power power circuit type (the au insulation layer contact point is a composite silver point), and it is not recommended to use a copper point. if it is used in a natural environment with high temperature and low humidity, it is recommended to use composite silver gold-plated dots.
7. according to the natural environment of the waterproof micro switch application, it can be divided into room or outdoor. indoor air is recommended to use pbt plastic material, outdoor pa66. 8. when using, pay attention to the surrounding natural environment, not too humid and cold and natural with corrosive vapor the environment is moderate.
9. after the durability test of the waterproof micro switch and after installation, it is recommended to rest for more than 1 hour to release the internal stress.
10. the altitude of the installation site does not exceed 2000m.
