on/off switch

on/off switch control the motor,suitable for woodworker,bench drill,tile saw,small machine tool and electric-driven equipments.     The series of electromagnetic switch has obtained many national patents for Utility Model and Design;has the merits compared with simolar products prevailing in the market including longer service life,larger rated working current and better sealing performance.    The outside plug preset in the switch can construct a comprehensive protection circuit with other outside devices like overload protection switch,travel switch,temperature control switch and Hall-effect switch,thus if the machine is in failure,the main power circuit will be automatically cut off by the switch to avoid accidents.The functions of cut-off and under-voltage protection of this electromagnetic switch can automatically cut off the main circuit once the power supply is cut off or under voltage,the switch can be normally operated only by re-pressing power-on button once the electricity is pulling through,thus the abnormal starting of electrical apparatus can be avoided.
