Claims

[Scope of utility model registration request]

In a door switch for an automatic door that is attached to the door tip of the door and detects internal pressure in response to external force acting on the door tip, the door tip switch is formed from an outer elastic covering and an inner elastic covering. At the same time, a gap is formed between the outer elastic covering and the inner elastic covering to form a double structure, and fixing pieces are fixed to the upper and lower parts of the inner hole of the inner elastic covering to form a hollow chamber. , an automatic door door switch characterized in that this hollow chamber is connected to a pressure switch via a communication tube.
