The contact switch for an elevator safety door has a simple structure, is convenient to use and is capable of being mounted in a mounting space of an existing narrow elevator door motor, thereby reducing the hidden danger of poor connection, ensuring that safety electrical components of an elevator door system are not influenced by the environment and loads, and thus ensuring a long-term safe operation of an elevator.
