I have a gate which can be opened with a remote control at the end of my driveway.
I have seen a device which indicates when the gate is open or closed. It was fairly
Simple, it was on a swivel. When the gate was closed it forced a "flag" into an up
Position. The "flag" was a reflector which could be seen from a distance.

My question is, Does anybody know where I can purchase such an item?

Thank You,

Bill

Something to consider, I recently made connections for Consumer installed Gate Operator.
Someone had installed 2 additional Limit Switches, to indicate Open/Close. New operator
Did not have room for 2 more. So I used unused terminal on N/O N/C switch, and one to the common. Works Great, except Red and Green are ON during transit. Which turned out
Not a problem. You could add switch so it would lite indicators, activate buzzer, both.
This was on a house that could not see Gate.

The terminals on N/0 N/C switchs I am speaking of, are the limit switches in operator.
Do you, or can you get 3 wires from house to operator?
