Waterproof micro switch can be uncommon because it is generally installed in the device Inside, it is not a device, but a precision-machined part, so today let's get to know the waterproof micro switch. The waterproof micro switch has a small contact interval and a snap-action mechanism. It is a kind of waterproof switch with a contact structure that performs the switch action with the force of the force, and is covered with a casing and has a driving rod outside.

Waterproof micro switch is mainly assembled by the following parts after corresponding processing:
1. Iron shell (material: generally iron; treatment process: treated with nickel electroplating or black pot to prevent oxidation)
2. Plastic handle (Material: Generally, POM material is used to realize the tact switch. If there is a fire retardant, flame retardant and high temperature resistance requirement, PA nylon material is often used. Processing technology Tact switch 220v: injection molding)
3. Terminals (Material: Phosphor bronze in general; Process: Electroplating silver)
4. Insulation bottom plate (Material: Bakelite; Process: Stamping)
5. Contact chip (Material: Phosphor bronze in general; Process: Electroplating silver)
6. Round wave beads (material: generally stainless steel; processing technology: electroplating nickel)
7. Slingshot (Material: Bronze; Process: Stamping)
8. Decorative oil (Material: red oil or green oil, a kind of chemical oil, smeared on the contact part of the terminal and the bottom plate to play a decorative role. Generally required to be non-toxic and environmentally friendly)

Waterproof micro switch usage tips
(1) When fixing the switch body, use M2 screws on the smooth surface with a torque of 0.098N·m or less. Also, to prevent loosening of the screws, it is recommended to use washers at the same time.
(2) Please note that in the free state, the action body should not directly exert force on the button or the exciter, and the button should exert force in the vertical direction during use.
(3) The operation setting after operation is based on 70[%] or more of the O.T. value. In the case of a switch, do not set the operating body at the operating limit position to prevent the life from being shortened by the opening and closing and over-travel caused by the shock.
(4) In the case of hand soldering, please use an electric temperature of 320°C with temperature adjustment to complete the operation within 3 seconds, and be careful not to apply force to the terminal part during the operation.
(5) It is recommended to use a low-power circuit type (Au-clad contact) when using it with a small current and voltage.
