摘要： In the gas blast switch disclosed, a first contact member in a gas pressure chamber moves from an open position out of contact with a counter-contact member toward the forward position of the counter-contact member until it hits the latter and drives it backwards against the force of a spring. The counter-contact member forms a gas seal with a valve sleeve that the countercontact member pushes back against the force of a second spring. A spring actuated retaining mechanism holds the sleeve in the back position. When the first contact member is moved into the open position the sleeve is held and the first spring moves the counter-contact member away from the sleeve to open the seal. This releases a flow of gas from the chamber past the contact member. The gas flow strikes a vane in the retaining mechanism. The response of the vane is to release the sleeve. The second spring drives the thus released sleeve into engagement with the counter-contact member to cut off gas flow.
