Ball switch how to use a more stable?

Currently many of the products in the use of ball switch, usage in general are as follows

1, for shaking switch: switch itself is a direction, product during shaking, ball rolling back and forth inside the tube produce switch signal, thereby triggering circuit. The general requirements of IC design and trigger twice to produce only one action, switch placed in anyway Chang Tong or normally open state, products are not triggered. This way of using the switch demand is not very high, generally ChanZhu switch, such as: SW - 200

2, for the alarm switch: when installed in a certain Angle with the switch, the switch is in on state, trembled, because the ball inside the pipe to beating, slightly to produce fault signals, the triggering action. For the use of this way, the sensitivity is high, the use of anti-theft products more, but the IC should make the corresponding Settings in order to avoid too sensitive, caused by the situation of the trigger.

3, Angle changes are applied: this way used to switch the demand is higher, general requirements such as 15 degrees tilt towards a product trigger action, some guests in the use of ball switch when it is Chang Tong, to another direction to disconnect trigger action, this assembly is the least desirable, because the ball switch in Chang Tong state is not so stable, like mercury switch contact conduction by mobile, thunder factors will have broken action, prone to trigger by mistake. And when installation should make switch is disconnected, tilt the generalist trigger action guide, so use switch products would seem to be more stable performance, and longer service life. As the two sides to the Angle of the sensor is applied to the two switch or with double of SW - 460 - dd, dd SW - 200 type (a related case: a customer is doing the digital photo frame, he has a product is usually put, function is normal, if the upside down time, the product will be music work and the picture will automatically turn, when he choose this company on account of a SW - 300 da. At ordinary times is to put the product switch is broken, then no problem. Product upside down, switch conduction trigger, product movement, question at this moment, because the product of pronunciation, vibration, ball bearing in the beating, the result is failure phenomenon, the guest the digital photo frame picture of the old produce reversal, beating products cannot be used.? Then we put forward a solution: use two switches, one is a reverse put, is to put a grain of another grain of open circuit, then the picture, the put a bead on the open, with music will not be afraid, IC set up until there is another guide communication, the picture will flip switch. And the vibration of the music is not big enough to conduction of vibration switch conduction of it, so the problem settled satisfactorily, customers using the product performance is very stable!)
