Compared with mercury switches, ball switches advantages which, along with the mercury switch will cause environmental problems, gradually being replaced by a ball switch. Here I will introduce the advantages of lower ball switch:

1, ball switch all materials can meet environmental requirements, and mercury switches `problem can not be achieved due to the material itself.

2, ball switch due to conduction mode is triggered through metal beads with the guide pin is energized to generate a signal, because the ball with a trigger guide pin contact area is small and the ball is active, so sometimes flash is turned off phenomenon, and mercury mercury switches are in contact with the trigger end, because mercury is a liquid, the contact surface is large and stable, generally conduction effect is more stable.

3, the switch is a metal ball shell, structural strength is good.
