formerly RI-07 Series Dry Reed Switch RI-07 Series Pico dry-reed switch hermetically sealed in a gas-filled glass envelope. Single- pole, single-throw (SPST) type, having normally open contacts, and contain- ing two magnetically actuated reeds. The switch is of the double-ended type and may be actuated by an elec - tromagnet, a permanent magnet or a combination of both. The device is intended for use in relays, sensors, pulse counters or similar devices.
