Abstract

The invention provides a linked contact switch which is arranged on a circuit board, wherein a first contact switch and a second contact switch are separately arranged on the circuit board; the linked contact switch comprises a first actuating part and a second actuating part; the second actuating part and the first actuating part are separately arranged, wherein the first actuating part is arranged above the first contact switch and elastically presses the first contact switch, and a first clamping groove is arranged on the first actuating part; the second actuating part is arranged above the second contact switch and elastically presses the second contact switch, and the second actuating part freely rotates relative to the circuit board; a first rotating arm is arranged on the second actuating part to change the rotary position of the second actuating part; and the first rotating arm is screwed into or out of the first clamping groove. In the linked contact switch of the invention, the first contact switch and the second contact switch are simultaneously closed by the first rotating arm, thereby realizing combination operation between the first contact switch and the second contact switch.

Description

【Technical field】 [0001] The invention relates to a linkage contact switch, in particular to a linkage contact switch which has a simple structure and can perform combined operations on different contacts. 【Background technique】 [0002] The contact switch belongs to the button switch, which is generally divided into a normally open switch and a normally closed switch. In some fields, it is necessary to open or close two contact switches at the same time during work. [0003] Mainland China Patent Application No. 95222408.9 discloses a compound multi-contact control switch, which includes a sliding bottom plate and a connecting plate with push pieces installed between the bottom shell and the cover with the wire seat, and the connecting piece and the connecting plate are fixed on the sliding bottom plate. The transition piece is also installed on the cover with a push-button or swivel sliding housing. The utility model has the advantage that when a plurality of the utility ...
