Claim:
1. An electronic indirect by-pass type semi-active mount comprising: a primary diaphragm dividing a lower fluid chamber, where a fluid in an upper fluid chamber to which an exciting force as external force is applied is circulated, into a primary lower fluid chamber where the fluid is circulated; a secondary diaphragm dividing the lower fluid chamber into a secondary lower fluid chamber where the fluid is circulated; a secondary diaphragm bracket blocking an atmospheric pressure formation peripheral space in which atmospheric pressure acts beneath the primary diaphragm and forming an atmospheric pressure formation central space in which atmospheric pressure acts beneath the secondary diaphragm; and by-pass channels in which a solenoid valve supplied with a current allows the atmospheric pressure formation peripheral space to communicate with an atmosphere whereas the solenoid valve blocks the atmospheric pressure formation central space from the atmosphere, and the solenoid valve which is not supplied with the current blocks the atmospheric pressure formation peripheral space from the atmosphere whereas the solenoid valve allows the atmospheric pressure formation central space to communicate with the atmosphere.
