Bestact’s high reliability provides stability for high-speed elevator operation. Since Bestact, a hermetically sealed glass contact power reed switch; was placed in service over 30 years ago; over 18 million have been used worldwide in applications such as transit train control, elevators and electric power facilities. Along with the construction of more high-rise buildings, the elevators that service them require more stable, reliable operation with ease of maintenance. Automatic monitoring of elevators now occur in hotels, apartment houses, department stores and railway yards around the clock...

Conventional reed switches are often used as an input device in conjunction with interface relay because contact reliability will go down in an adverse environment or when neglected for a long time. Bestact is a hermetically sealed contact, which exhibits no environmental or deterioration over time. This leads to long-term stable contact reliability. Therefore, no interface relay is needed and direct input is achievable while reducing control circuitry costs.

detection. When the car moves in either and up or down direction, the stop target Vane enhances the magnetism of magnetic proximity switch on the elevator car turning it on (or off) and sending a signal to the elevator control system. DOWN SIDE FACE Direction detecting switch; operates at the beginning along with the movement of the car and detects which the car is moving up or down. Door opening command switch; operates just before the movement of the car and commands to open the door. Landing floor detecting switch; movement of this switch detects the coincidence of the elevator floor with...
