Abstract

A double-pole double-throw radio-frequency relay with auxiliary contacts comprises a base and a cover. An electromagnetic system is fixed above a contact system which is fixed above the base, and the contact system and the electromagnetic system are both positioned in the cover. The auxiliary contacts are arranged below the electromagnetic system. A function of shifting between the auxiliary contacts and radio-frequency contacts of the relay under excited and unexcited states is realized, and monitoring or instruction of contact states of a main contact is realized through the auxiliary contacts. The double-pole double-throw radio-frequency relay can be used for signal transmission and switching circuits in communication equipment and is capable of realizing line switching during monitoring of contact reliability conditions of the main contact or during signal transmission.

Description

technical field

[0001] The invention belongs to the technical field of relay manufacturing, in particular to a double-pole double-throw radio frequency relay with auxiliary contacts. Background technique

[0002] The existing double-pole double-throw radio frequency relay cannot monitor or indicate the contact state of the contacts, and it is difficult to meet the needs of users. Contents of the invention

[0003] The technical problem solved by the present invention is to design a double-pole double-throw radio frequency relay with an auxiliary contact, the main contact is double-pole double-throw, and the auxiliary contact is also double-pole double-throw. The contact state of the main contact is monitored or indicated through the auxiliary contact, and the circuit used for signal transmission and switching in communication equipment has the ability to monitor the reliability of the contact of the main contact or perform line switching while signal transmission.
