Touch control dual-channel output switching device

The invention discloses a touch control dual-channel output switching device, which is used for multi-path switching output of instrument signals and comprises a key touch module, a driving module, a switching module, a power supply module, a signal input interface and a signal output interface, after the key is touched, the key touch module outputs + 3.3 V level to the input end of the driving module according to capacitance change of the touch disc, the output end of the driving module is connected to one side of a coil of the relay, and finally, the contact end and the normally closed end of the relay are respectively connected to the double-channel series-parallel circuit, so that various signal output modes are realized. The touch control dual-channel output switching device provided by the invention solves the problem of how to realize multi-path and multi-channel input and output rapid switching of industrial instrument signals, analog quantity signals and the like, and has strong signal anti-interfere
