Micro dry-reed switch hermetically sealed in a gas-filled glass envelope.
Single-pole, single-throw (SPST) type, having normally open contacts,
and containing two magnetically actuated reeds.
The switch is of the double-ended type and may be actuated by an
electromagnet, a permanent magnet or a combination of both.
The device is intended for use in relays, sensors, pulse counters or
similar devices.

The switches are tested in accordance with "IEC 68-2-27",
test Ea (peak acceleration 500 G, half sinewave; duration
11 ms). Such a shock will not cause an open switch (no
magnetic field present) to close, nor a switch kept closed by
an 80 AT coil to open.

The leads should not be bent closer than 1 mm to the glass-
to-metal seals. Stress on the seals should be avoided. Care
must be taken to prevent stray magnetic fields from influ-
encing the operating and measuring conditions.
Note 1: Switching higher currents is possible depending on signature of the load.
