Micro Switch Waterproof Introduction
Waterproof micro switch is a kind of waterproof
switch with tiny contact interval and quick-action
mechanism, contact structure of switching action
with specified stroke and specified force, covered
with enclosure, and its external drive lever.
Features of the waterproof micro switches
This micro switch has a waterproof rating of IP*7,
which is a high waterproof performance, and the
switch body is miniature in size, light in weight,
good in feel and long in life. Besides, there are
various choices of shapes and heights
(custom micro switch can be made according to
customers' requirements), and it is easy to
install.
Application of micro switch waterproof
Micro switch waterproof is widely used in various
cold, wet, dusty and various harsh environments.
Such as automobile, spraying equipment, etc.
