The invention discloses an automatic wire cutting control system of a reed switch. The automatic wire cutting control system comprises a feed device, a shearing device, a feeding device, a first material pushing device, a second material pushing device, a power device, a first sensor, a second sensor and a control device. The feeding device is used for feeding. The feed device is used for feed. The shearing device is used for shearing. The first material pushing device comprises a first plate frame and a first material pushing head arranged on the first plate frame. The second material pushing device comprises a second plate frame and a second material pushing head arranged on the second plate frame. The power device is used for driving the first material pushing device and the second material pushing device to get close to or away from each other. The first sensor is used for detecting whether the end face pressure value of the first material pushing head changes or not. The second sensor is used for detecting whether the end face pressure value of the second material pushing head changes or not. The control device is connected with the feed device, the shearing device and the power device and controls the action of the feed device, the shearing device and the power device. The automatic wire cutting control system is high in automation degree.
