DKS DoorKing 1812-005 Switch Push Button

DKS 1812-005 Switch push button is an electric push button switch that is a replacement part. Push button switches work by applying pressure to the button, which depresses the internal spring and contacts, and causes stable contacts at the bottom of the switch to touch. This process either opens or closes the electrical circuit. When the button is released, the spring mechanism returns to its original position, causing the contacts to separate and break the circuit.
