Abstract

An inductive switch comprises a ceramic body, a first conductive unit, a second conductive unit and a conductive part, wherein the ceramic body is formed by stacking and sintering a plurality of ceramic green bodies; the first conductive unit and the second conductive unit are formed by arranging metal materials on the ceramic green bodies; the ceramic body comprises a middle layer part, a lower layer part and an upper layer part which define a cavity, the middle layer part is provided with an inner surface, and the lower layer part is provided with a blind hole opened towards the cavity. The first conductive unit comprises a first conductive layer covering the inner surface of the middle layer part. The second conductive unit comprises a second conductive layer which is at least arranged in the blind hole and is in a downward concave shape. The conductive part has conductivity and is located in the cavity in a rolling mode. The conductive part is used for forming a current path with the first conductive layer and the second conductive layer. The ceramic body is formed by stacking and sintering the ceramic green bodies, so that the inductive switch can break through the existing limitation, and the overall size can be effectively reduced.

Description

technical field [0001] The invention relates to a switch, in particular to an inductive switch. Background technique [0002] The existing ball sensor switch is used to set on a circuit board, and the internal balls are used to sense the change of the angle, and the sensing result is transmitted to the circuit board, so it can be used in security alarm devices, anti-theft devices, energy Sensitive action toys and more. However, the existing ball-type inductive switch has many parts and its volume has its limit, so it is difficult to reduce it. Contents of the invention [0003] The object of the present invention is to provide an inductive switch capable of reducing parts and volume. [0004] The inductive switch of the present invention includes a ceramic body, a first conductive unit, a second conductive unit, and a conductive member. [0005] The ceramic body is made by stacking and sintering a plurality of ceramic green bodies. The ceramic body includes a middle par...
