Adopt technique scheme, can be entered in housing between button and housing by anti-sealing well by the sealing shroud arranged, thus switch stable performance can be ensured.
Further setting of the present utility model: button lower end is provided with posting, described sealing shroud upper end is set on described posting, and posting lower end is outward extended with fixture block, and described fixture block and sealing shroud inwall are conflicted.
Adopt above-mentioned further setting, the button of this structure and sealing shroud connected mode, make button when pressing, and is not easy to be separated with sealing shroud, improves its sealing further.
Setting further more of the present utility model: the sidewall between described sealing shroud top and bottom is that corrugated is arranged.
Adopt and above-mentionedly to arrange further again, can make when being pressed to side by button like this, the sealing shroud of button opposite side can not be strained, and has enough surpluses, more durable.
Further setting of the present utility model: be provided with mounting bracket in described housing, described mounting bracket is provided with the hole passed for slide upper end, is provided with water proof ring between described slide and support.
Adopt and above-mentionedly further to arrange, even if part water is from entering in housing between housing and button, water proof ring also can enter the service behaviour affecting contact below mounting bracket by anti-sealing well, improves its sealing effectiveness further.
Further setting more of the present utility model: conflict in described water proof ring and slide upper end, mounting bracket is provided with the annular groove placed for water proof ring periphery, and the periphery of described water proof ring has been installed with pressure ring.
Adopt and above-mentionedly further to arrange again, the water proof ring locate mode of this structure, structure is simple, good airproof performance.
Further setting more of the present utility model: be provided with steel ball between described slide lower end and springboard, be provided with spring in described slide, both ends of the spring is conflicted with steel ball, slide respectively.
Adopt and above-mentionedly further to arrange again, be the fulcrum that springboard swings, rub little by steel ball, it is convenient to swing, and long service life is easy to use.
