Abstract
A multilayer angle tilt switch comprises a housing, a photoelectric group and a rolling assembly. The housing is provided with a first ring surface and a second ring surface which define a cavity. The included angle of the first ring surface is larger than the included angle of the second ring surface. The photoelectric group is provided with an optical emitter and an optical receiver which are oppositely arranged at the two sides of the cavity. The photoelectric group is used for generating an optical signal passing through the cavity. The rolling assembly is accommodated in the cavity and follows the first ring surface and the second ring surface to roll between an optical-signal-blocking off position and an optical-signal-opening on position. Therefore, with the relatively-wide included angle of the first ring surface, the rolling assembly does not be blocked when the housing inclines; and with the relatively convergent angle of the second ring surface, the rolling assembly can successfully break away from the optical axis according to preset inclination angles, thereby improving sensitivity and smoothness during moving.
