介绍 Introduction
BS03电梯双稳态开关用于电梯的平层和井道，为电梯升降的限位控制用。由于采用了干簧管技术，克服了机械式开关容易损坏的缺陷，具有高可靠性、长寿命、响应迅速、不耗电、安装接线方便等优点。
In the elevator industry, magnetic reed switches are used for positioning and control. They are preferably used where mechanically actuated limit switches no longer function satisfactorily due to unfavourable operating conditions such as high or low start-up speeds, high switching frequencies, strong dust or dirt influence, high humidity, chemical atmospheres or large fluctuations in operation intervals.
