System details

The system consist two push buttons and a controller. When both the push buttons are pressed, the output relay from the controller gets ON. When both the switches are operated, the output relay gets on for 1 sec and automatically gets off. The controller will operate a solenoid valve which in turn will operate a pneumatic cylinder. This pneumatic cylinder is used to pull the DOG of the rolling key press. Once the DOG is released for position, the stroke is completed.

The stroke is allowed once only when both the switches are pressed at a time. The multiple strokes will not be continued if both the push buttons remains continuously pressed. You have to release the push button and press again. So both the hands of the operator are engaged to operate press.
