ABSTRACT:
A remote control apparatus for power washers includes a water line having a flow control switch device which is in series therewith. The flow control switch device includes an electrical flow responsive switch which is actuated in response to water flow through said line and is deactuated in response to the absence of such flow. A time-delay starting switch device is connected to the flow responsive switch and includes a starting switch which is actuated after a predetermined period of time in response to actuation of the flow responsive switch and is deactuated directly in response to deactuation of the flow responsive switch. The starting switch device further includes a timer for operating the starting switch which is activated in response to actuation of the flow responsive switch and is reset upon deactuation of the flow responsive switch. A relay for controlling a motor operated pump is actuated and deactuated responsive to the operation of the starting switch. A time-delay stopping switch device is connected to the flow responsive switch and includes a stopping switch which is actuated after a predetermined period of time in response to deactuation of the flow responsive switch and is deactuated directly in response to actuation of the flow responsive switch. The stopping switch device further includes a timer for operating the stopping switch which is activated in response to deactuation of the flow responsive switch and is reset upon actuation of the flow responsive switch. The aforesaid relay is responsive to actuation and deactuation of the stopping switch for controlling correspondingly the water pump.
