ABSTRACT:
A door switch apparatus is provided in an automatic vending machine to cut off electric power to exposed electrical devices mounted on the inside face of the vending machine's service door when the door is opened. The switch is constructed with safeguard members to protect against inadvertent contact by a service person, ensuring that the exposed electrical devices will not be electrified until the service person closes the service door.
