Below is a side internal view of the EL mechanism and the associated anti-pumping component.

When the opening pushbutton or coils are activated the opening shaft lever pushes down on point C of the anti-pump device.

This causes the device to side down slot D in direction of arrow B.

Then the trigger portion A moves out from between the closing push-button and the closing shaft lever.

So if the closing button or signal is held active and the opening button or signal is then activated.

The trigger A will pull out from between closing shaft lever and the closing push button.

Once the open signal is released the trigger A will come to rest under the closing push-button and will

not return between the closing shaft lever and closing push-button until the button or closing command is released.

The closing push button is operated by the closing coil (MC) directly by the shaft closing device.

This allows the anti-pumping device to prohibit closing by manual or electrical means.
