Abstract
A pressure responsive switch performing switching operation for converting pressure variations into electric variations is disclosed in which the actuating pressure of a snap switching member is adjusted by changing the contact pressure between a pressure applied member and the snap switching member which is in contact with the pressure-applied member. The gap between the break contact of the pressure responsive switch is adjusted thereby to adjust the difference between the pressure between the make contact of the switch when it is closed and the pressure between the break contact of the same when it is closed.
