1. The electrical characteristics of the switch with mercury switches are similar but not dangerous mercury switches and environmental issues and have the same characteristics as the wizard rock single pass the assembly is more convenient and safe to use; 2. The operating characteristics: in the stationary state switch when (ON) below the level of the end of 15 degrees the switch is in the ON state; when the (OFF) side lower than 15 degrees the switch is in OFF state; when subjected to external shaking while shaking force reached or when the conduction angle is set in the range the conductive pin electrical characteristics will produce short or continuous conduction. 3. When the electrical characteristics of the open state to be restored (OFF) switch to set the environment must be static and (OFF) below the level required to set up the open end angle; 4. The switch all the materials used are environmentally friendly raw materials manufacturing meet the ROHS requirements; 5. When the switch is OFF side angle of 15 degrees below the horizontal while shaking difficult to trigger conduction; 6. The trigger switch for low current circuit does not apply when the power switch; 7. This switch is a sealed package dustproof waterproof; 8. The ball switch series switch conduction best results the highest sensitivity
