Reed Switches

　 Our broad product line allows the customer to select a product to suit the intended application and purpose, for everything from low-voltage signal lines to high-voltage power lines.　 　

Oki reed switches have extremely high-quality due to our proprietary technologies -- contact surface deactivation treatment, high-performance automatic sealing machines, and contact resistance measurement based on the flux scanning (FS) system. These technologies have earned us the top market
share in Japan. Also, our broad product line allows the customer to select a product to suit the intended application and purpose, for everything from low-voltage signal lines to high-voltage power lines

The reed switches comprise two ferromagnetic reeds placed with a gap in between and hermetically sealed in a glass tube. The glass tube is filled with inert gas to prevent the activation of the contacts. The surfaces of the reed contacts are plated with rhodium or iridium.

The reed switch is operated by the magnetic field of an energized coil or a permanent magnet which induces north (N) and south (S) poles on the reeds. The reed contacts are closed by this magnetic attractive force. When the magnetic field is removed, the reed elasticity causes the contacts to open the circuit.
The transfer type reed switch is normally ON, due to mechanical bias of the common (COM) lead, which is between the normally closed (N.C) reed contact and the normally open (N.O) reed contacts.

When an external magnetic field is induced, the N.C blade is not affected because it is non-magnetic but the COM lead is attracted by the N.O lead and moves. When the magnetic field is removed, COM lead again moves to the N.C lead by mechanical bias. .
