A remote actuator means for a pressure-switch operated device such as a conventional latching relay acting as as on-off switch for an electric motor is provided which comprises a remote spring-loaded actuator cap connected to the device to be actuated via an air actuator conduit. The air actuator conduit communicates with the atmosphere through a vent provided only in the actuator cap. When the operator manually depresses the actuator cap, he or she will automatically cover the vent opening, causing the heretofore open system to be temporarily closed. As the actuator cap is depressed, it compresses air within the now temporarily closed system, causing the latching relay to be “pulsed”, which, in turn, activates or deactivates whatever the relay is electrically connected to, e.g., an electric motor driving a water pump in a whirlpool bath system. Because the pressure-switch actuating or deactuating the relay or other device is always open to the atmosphere and is temporarily closed only for actuating or deactuating purposes, the relay, or other device, will not be prematurely triggered by increase in pressure, which would otherwise be the case if the pressure-switch and actuator cap existed in an essentially closed system－as in the prior art.

A remote actuator means and a pressure-activated switch, which comprises: a housing, mounted at a location remote from the switch; an air actutator conduit having first and second ends, the first end being connected to the pressure-activated switch; and an actuator cap means retained within said housing and movable therewithin from a first position to a second position, including a vent means to the atmosphere, spring means which extend substantially within the actuator cap means, and means operatively connecting the actuator cap means and the spring means to the second end of the air actuator conduit, such that the air actuator conduit to which the acutator cap means are operatively connected are normally vented to atmosphere through the vent means, and such that the vent means are adapted to be manually blocked while simultaneously manually moving the actuator cap means to the second position thereof so as to generate an increase in air pressure in the air actuator conduit which in turn activates the switch.
