The vibration switch, the correct name should be called the vibration sensor, is an electronic switch that transmits the induction result to the circuit device when the vibration force is sensed, and makes the circuit start to work. Others call it a vibrating switch, others call it a slide switch or a shake switch, and so on, but these names are not entirely correct. The names in the industry are generally divided into two categories, spring switches and ball switches. In fact, strictly speaking, the vibration switch should simply refer to the spring switch, not including the ball switch. The name of the vibration switch seems to be just a typo caused by the homophony of "vibration" and "quake". Due to a long time, it is also recognized by people as a misunderstanding. Strictly speaking, the term vibration switch is wrong. Other names such as slide switches, shake switches, etc., should refer to ball switches. For convenience, the industry generally refers to the two categories of spring switches and ball switches collectively as vibration switches. Vibration switches are mainly used in electronic toys, small household appliances, sports equipment and various anti-theft devices and other products. The vibration switch has become an indispensable electronic component in many electronic products because of its flexible and sensitive triggering. 
 

Vibration switch SW-200.
1. This switch is made of metal. The electrical characteristics are similar to those of a mercury switch, but without the danger and environmental problems of a mercury switch, and with the same characteristics of a one-way channel when shaking, it is easier and safer to assemble and use.
2. Working characteristics: The gold end is the ON trigger end and the silver end is the OFF open end. When shaken by external forces and the appropriate shaking force is reached or when the angle set at the gold end is lower than the appropriate angle at the horizontal, the electrical characteristics of the conductive junction will produce a short period of on or continuous on (ON) state, and when the electrical characteristics are to return to the open state (OFF), the switch must be set in a static environment. The silver end must be set at an angle of 10 degrees below horizontal.
3. When the switch is set horizontally, it can be easily triggered by shaking, while when the silver end is set downwards, it is extremely difficult to trigger by shaking. 4. This switch is suitable for triggering low current circuits and is not suitable for use as a power switch.
5. The appearance of this switch is encapsulated in heat shrink tubing to protect it from dust and moisture.
6. SW-200D double ball switch has a long on time.
7. SW-20014 extended type double bead switch has a better on-off effect. 

Vibration switch SW-180.
1. The switch is open (OFF) at rest. When it is hit by an external force and reaches the appropriate vibratory force, or when the moving speed reaches the appropriate eccentric force, the conductive pin will produce a momentary ON state, causing the electrical characteristics to change, and when the external force disappears, the electrical characteristics return to the open (OFF) state.
2. Non-directional, can be triggered at any angle.
3. Model number with P at the end is completely hermetically sealed for waterproof and dustproof. 
4. The trigger sensitivity can be selected according to the needs of the circuit. 
5. The switch is suitable for triggering small current circuits.
 
Vibration switch SW-520D.
1.The switch is made of metal and its electrical characteristics are similar to those of a mercury switch, but without the danger and environmental problems associated with mercury switches.
2. Working characteristics: As shown in the installation diagram (ON) the conduction degree is 90 degrees and (OFF) the opening angle is 180 degrees. When shaken by external forces and the appropriate shaking force is reached, or when the setting angle is lower than the 90 degree range of the conduction angle, the electrical characteristics of the conductive pin will produce a short time foot conduction or continuous conduction.
3. When the electrical characteristics are to be restored to an open (OFF) state, the switch must be set in a static environment and the (OFF) open terminal must be set at an angle lower than the horizontal angle.
4. When the switch is set at an angle of 30 degrees below horizontal, it is extremely difficult to trigger when shaken. 
5. This switch is suitable for triggering low current circuits and is not suitable for use as a power switch.
6. The switch is hermetically sealed to protect against dust and moisture.
