What Are The Precautions For The Miniature Micro Switch

Many people may have never heard of a micro switch, let alone what it is. In fact, in our lives, we need to use it frequently. As long as it is an electronic device, it is inseparable from it. Today, let’s learn about the principle of the miniature switch and the related content of the precautions for the miniature switch. Let’s take a look.

1.The Principle Of The Miniature Switch

The miniature switch mechanism is composed of minute contact intervals and quick movements. Those devices that need to switch circuits frequently are automatically controlled and protected. They are usually widely used in electronic equipment, instrumentasi, sistem kuasa, dan lain-lain. In many fields such as household appliances, aeroangkasa, tanks, dan lain-lain., its principle is that the external mechanical force passes through the transmission element. Then the force is applied to the action reed. When the displacement of the action reed reaches a critical point, it will produce Instantaneous action. The moving and fixed contact at the end of the action reed can be quickly connected or disconnected, and the reverse auction can be completed instantly.

2.What Are The Precautions For The Miniature Switch?

1. If it is the main body of the fixed switch, use M2 small screws and then place the small screws on the smooth surface with a torque of 0.098N m or less to fix it. Sebagai tambahan, to prevent the screws from loosening, it is best to use washers under the screws.
2. In the free state, the action body must pay attention not to applying force directly to the button or exciter but to the vertical direction corresponding to the button when in use.
3. After the miniature switch is activated, the action set should be based on more than 70% of the OT value. When the switch is turned on, the action body cannot be directly set to the position of the action limit. Jika tidak, it is accessible to The opening and closing due to the shock occurring, which will shorten its service life.
4. Even if the action characteristics of the miniature switch jump up and down 20% of the specification value, it will not cause a malfunction due to changes.
5. In the case of welding with a micro switch hand, remember to use the electric temperature with a temperature adjustment of 320°C max.), complete the operation within 3 seconds, and do not put the terminal part in the process of completing the operation. Exert force.
6. If the miniature switch is used under a small current and voltage, it is recommended to use a low-power circuit instead of a high-power one.
