    • PURPOSE: Electro-mechanical switching device and method of manufacture are provided to have an electrical switch having electrical contact arm using cheap contact pieces which get a simple shape and planar bottom surface. CONSTITUTION: To make electrical contact arm, a contact tape(1) having a specified thickness and width is cut in single contact pieces by cutting mechanism(4). The contact tape(1) is composed of contact material and coated on one side by a braze alloy armature. A pair of cut contact pieces(3A,3B) are centered over both sides of through hole(6) with the braze alloy layer set in metal blade(5). To contact the respective surrounding surfaces of the metal blade(5) by each contact pieces(3A,3B) with the through hole(6) covered in both sides of the metal blade(5), a contact piece's cross section area is larger than the through hole(6). A pair of electrode are applied on surface layer of the contact pieces. After cut off current, the electrodes are maintained enough time in position, and a braze alloy could be solidified. Thus, contact pieces (3A,3B) could be bonded each other. As an excess braze material fills up the through hole(6) completely or has the through hole(6) join enough, it is accomplished.
    • 目的:提供机电开关装置及其制造方法,使具有电接触臂的电气开关使用廉价的接触片,其形状简单,底面平坦。 构成:为了形成电接触臂,通过切割机构(4)将具有规定厚度和宽度的接触带(1)切割成单个接触片。 接触带(1)由接触材料组成,并通过钎焊合金电枢在一侧上涂覆。 一对切割接触片(3A,3B)在钎焊合金层设置在金属刀片(5)中的通孔(6)的两侧对中。 通过每个接触片(3A,3B)与金属刀片(5)的两侧覆盖的通孔(6)接触金属刀片(5)的各个周围表面,接触片的横截面面积大于 通孔(6)。 一对电极施加在接触片的表面层上。 在切断电流之后,电极保持足够的时间就位,钎焊合金可以固化。 因此,接触片(3A,3B)可以彼此接合。 由于过多的钎焊材料完全填满了通孔(6),或者使通孔(6)足够的接合,所以完成了。
