An object of the utility model is to overcome prior art's defect, provide a simple structure, stable performance are reliable, the assembly is convenient, small, the convenient auxiliary switch of wiring.
In order to achieve the above object, the present invention provides an auxiliary switch with convenient connection, which comprises a base, a cover plate disposed on the base, and a switch assembly disposed in the base, wherein the switch assembly comprises a contact holder movably disposed in the base, a reset spring disposed between the base and the contact holder, a plurality of normally open moving contacts cooperating with the contact holder, a plurality of normally closed moving contacts cooperating with the contact holder, a plurality of contact springs disposed between the normally open moving contacts and the normally closed moving contacts, and a plurality of static contacts disposed on the base respectively, one end of each static contact is provided with a normally open contact portion and a normally closed contact portion, the normally open contact portion is provided with a normally open static contact cooperating with the normally open moving contacts, the normally closed contact portion is provided with a normally closed static contact contacting with the normally closed moving contacts, and the other end of the normally closed static contact is provided with a plug-in portion, the inserting part is provided with an inserting terminal.
The beneficial effect of above-mentioned structure is: the normally open contact part and the normally closed contact part are arranged at one end of the static contact, so that the wire doubling is not needed, the structural design is simpler, the plug-in terminal is arranged at the other end of the static contact, the plug-in type connection of the static contact and the wire can be realized, and the wiring is more convenient. Therefore, the auxiliary switch has the advantages of simple structure, stable and reliable performance, convenience in assembly, small size and convenience in wiring.
Particularly, one end of the plug terminal is provided with a crimping part connected with a wire, the other end of the plug terminal is provided with a plug cavity for the plug part to be inserted, and the plug terminal is provided with a contact spring sheet which is abutted against the plug part. The plug-in cavity is formed in the plug-in terminal and is plugged with the fixed contact, so that plug-in type wiring of the auxiliary switch is achieved, wiring is more convenient, and the contact elastic piece is arranged on the plug-in terminal, so that the plug-in terminal can be ensured to be more reliably contacted with the fixed contact, and the working reliability of the auxiliary switch can be improved.
Particularly, the normally open contact part, the normally closed contact part and the inserting part corresponding to the static contact in the base are respectively provided with a clamping groove which is matched with the normally open contact part, the normally closed contact part and the inserting part, and the normally open contact part, the normally closed contact part and the inserting part are respectively clamped in the clamping grooves to form clamping matching of the static contact and the base. The static contact is connected with the base in a clamping matching mode, so that the base and the static contact can be assembled conveniently, and the assembly is more convenient.
