Abstract
A combination pressure switch including a pressure switch moveable between open and closed positions in response to a working pressure of a fluid, the pressure switch including a contact assembly having first and second terminals electrically connected through a current-carrying member movable by the pressure switch, and a manual switch configured to move the current-carrying member independent of the movement of the pressure switch.
Claims17
A combination pressure switch, comprising:
- a pressure switch moveable between an open position and a closed position in response to a working pressure of a fluid, the pressure switch comprising a contact assembly including a first terminal, a second terminal, and a current-carrying member moveable between an open configuration electrically disconnecting the first and second terminals and a closed configuration electrically connecting the first and second terminals, wherein the current-carrying member is moved from the closed configuration to the open configuration by movement of the pressure switch to its open position in response to a working pressure of a fluid;
- and
- a manual switch configured to move the current-carrying member between its open and closed configurations independent of the movement of the pressure switch in response to a working pressure of a fluid.

- an unloader valve moveable between a closed position and an open position by movement of the pressure switch in response to a working pressure of a fluid;
- and
- a manual switch configured to move the current-carrying member between its open and closed configurations and move the unloader from its closed position to its open position independent of the movement of the pressure switch in response to a working pressure of a fluid.
