Title:
DUAL-CONTROL SWITCH
Document Type and Number:
WIPO Patent Application WO/2020/238177
Kind Code:
A1
Abstract:
A dual-control switch (100), which falls within the technical field of electronic devices. The dual-control switch (100) comprises an intelligent switch (110) and a control switch (120). The intelligent switch (110) comprises a processor (10), a relay (11), a current detection module (12) and an intelligent switch common port (13), wherein the processor (10) is connected to the relay (11) and the current detection module (12), respectively. The current detection module (12) is used for acquiring the current between a common terminal of the relay (11) and a common terminal of the control switch (120); and the processor (10) can determine the state of the dual-control switch (100) according to the situation regarding the current, acquired by the current detection module (12), of the intelligent switch (110) in different states, without needing to further determine the state of the control switch (120). Therefore, compared with the prior art, the dual-control switch (100) can be intelligently controlled merely by replacing one single-pole double-throw switch in a traditional dual-control switch with the intelligent switch (110), and thus, the transformation difficulty and transformation cost are reduced.
