ABSTRACT:
Apparatus for testing an electrical switch responsive to fluid under pressure and a solenoid valve that controls the flow of fluid under pressure. Fluid under pressure is injected into a socket holding the switch to be tested. The magnitude of the pressure is predetermined in accordance with the rating of the switch. An electrical circuit is connected to the switch to determine whether the switch opens and closes at the rated range of the switch. A solenoid valve communicates with the socket. Fluid under pressure is conducted along a path. The solenoid valve is disposed in the path of fluid flow to control the flow of fluid under pressure. The electrical circuit is connected to the solenoid valve to energize and deenergize the same, thereby opening and closing the valve. A meter communicating with the flow of fluid under pressure indicates whether the solenoid valve is operating properly.
