<p>A signal generating valve and timer assembly includes a valve slide and a controller. The controller is coupled to the valve and is adapted to engage the valve to move the valve from a first position to a second position. The valve generates a first signal in at least one of the first or second positions. Movement of the valve slide from the first position to the second position engages an actuator device to activate a switch on the timer to start the timer running for a pre-programmed time period. The timer generates a second signal at the expiration of the selected time period.</p> |
