Vibrate Magnet Contactor
Vibrate Magnet Contactor can detect the vibration and respond the host. It is very simple structure but can work very perfectly without any maintanence. Vibrate Magnet Contactor can compete very well against other Switches.
The vibration switch, the correct name should be called shock sensor, that is, in the sense of the magnitude of the shock force will be sent to the circuit device sensing results, and make the circuit start working electronic switch. Some people call it a vibration switch, and some people call it a slide switch or a rocker switch. In fact, these names are not completely correct. The industry name is generally divided into two categories, spring switch and ball switch. In fact, strictly speaking, the vibration switch should simply refer to the spring switch and does not include the ball switch. The name “vibration switch” seems to be just a typo caused by the homophony of “vibration” and “quake”. Because of the long time, it is a kind of common mistake that people recognize. Strictly speaking, the name of the vibration switch is wrong. Other names such as slide switches, rocker switches, etc. should all refer to ball switches. For the sake of convenience, the industry generally also unifies the two types of spring switch and ball switch as a shock switch. Vibration switch is mainly used in electronic toys, small household appliances, sports equipment and various types of anti-theft devices. Because of its flexible and sensitive triggering, the shock switch has become an indispensable electronic component in many electronic products.
From a professional point of view, we can be divided into two major categories of spring switches and ball switches. Two major types of switches have two more important index characteristics, sensitivity and directionality. The sensitivity of the spring switch refers to different products. In the actual device, there will be a difference in the magnitude of the induced vibration force. This difference is called sensitivity. Users will choose different types of vibration sensors to meet the sensitivity of their products because of the needs of different products. For example, if a toy is shaken slightly on the hand and a ball is thrown on the ground or wall, different induction spring switches will be required to induce the vibration force to match the electronic circuit. Directionality refers to the direction of force, and the direction of force is roughly divided into three-dimensional, six-sided, up-down, left-right, and front-rear six-sided. In general products, only the sensitivity requirement does not have a directional requirement. Therefore, it is necessary to first understand the use of the user's product in order to recommend the user to use that type of spring switch. The biggest difference between the ball switch and the spring switch is that: the spring switch is the size of the induced vibration force or centrifugal force, and it is best to use it upright. The ball switch is the change of the sensing angle, and it is best to use the tile. The sensitivity of the ball switch is the size of the sensing angle, and the sensing result is transmitted to the circuit device to start the circuit. In the actual device, there will be differences due to different product sensing angles, which is called sensitivity. Users will need different ball angle switches to meet the sensitivity of the product because of the needs of different products. For example, if a cup is picked up by hand at a slight angle, the circuit device must make the IC start LED flash or emit a sound. Customers will require different sensor ball switches to sense the angle and match the electronic circuit. The directionality of the ball switch refers to the direction of the tilt angle, and its direction is roughly two sides.
REED SWITCH CAN WORK AS THE GAS SENSOR
The reed switch is an excellent substitute for various fuel level sensors for vehicle tanks. There are two types of oil (liquid) sensors: one is a sliding potentiometer as the basic detection element, which is driven by a float and then the potentiometer. The ohmmeter is used to test its resistance value so as to achieve the purpose of displaying the oil level. However, when the grease covers the potentiometer, its resistance value will change, causing too much error and even being unusable. Such a fuel tank sensor becomes a very short-lived one. Damage.
The other is the use of inductors as the basic detection element. It uses a float to drive the inductor and change the oscillating frequency of the oscillating circuit. Then the frequency is used to measure the oil (liquid) position. However, its structure is complicated, the debugging is troublesome, the cost is high, and the price is expensive and cannot be widely used. Therefore, the use of dry-reed pipes with long life, safe and reliable, non-sparking and other characteristics of the production of liquid level sensors, is now a variety of vehicle fuel tank level sensor an excellent alternative.
