Abstract
A dust and moisture free switch includes a hollow casing, a contact pole device, a control plate and an isolation part. The contact pole device is inserted to the bottom of the casing with a stationary pole and a support pole being inserted into and locating at a respective pole hole and an arc pole being attached to the top of the support pole such that the arc pole can swing leftward and rightward. The control plate is joined to the upper portion of the casing and has the bottom thereof being arranged with a central hollow post to fit with an extensible stir lever, which has a bottom thereof contacting with the arc pole. The isolation part is made of soft high molecular plastic material and passed through by and fitting with the stir lever so as to be located at and closely joined to the inner wall of the casing to perform a function of blocking dust or moisture to enter the bottom of the casing. The stir lever can slide on the arc pole in case of an end of the control plate being pressed such that the arc pole can touch or detach from the stationary pole selectively to perform power on or off.
