This is an emergency button used in a railroad crossing alarm. I purchased it at a railroad parts sale, but I am selling it to organize my collection. The red lamp on the side is lit, but the buzzer that should sound when the button is pressed has been removed. Therefore, even if you connect the wires as they should be, not all parts will function. I recommend this for those who can perform maintenance themselves. Please note that we are not responsible for accidents, damage, or malfunctions during shipping.
