Abstract
Swivel actuating pressure switching devices and methods are described herein that include a shorting member that translates and rotates into contact with one or more terminals in response to the application of a specified pressure to a piston included in the switch. The rotation of the shorting member with respect to the one or more terminals can be controlled by a receptacle that can include flutes, which guide the rotational movement of the shorting member in response to fluid pressure that causes the translation of the piston.
