BR17
Half-Size Crystal Can
Welded • DPDT
Dry Circuit to 2 Amps
Welded • DPDT
• UNIVERSAL CONTACTS…permit operation from dry circuit to rated load with the same contact set.
• UNIQUE HEAT SINK/MAGNETIC FLUX CONDUCTOR…improves heat dissipation characteristics— insures
lower temperature rise.
• SPECIALLY-DESIGNED MAGNETIC CIRCUIT…locates armature inside coil for more efficient switching action.

Notes:
5. Contacts were placed in the position shown by placing
voltage with the polarity shown on the indicated coil
(reset). To switch contacts, a voltage of indicated
polarity must be applied to the other coil (Latch).
1. For case grounded loads and other ratings, consult the
factory.
2. For applications requiring other shock and vibration
levels, consult the factory.

voltage with the polarity indicated on the coil. To switch
contacts a voltage of the reverse polarity must be
applied to the coil.
4. Relay contacts which have switched high level currents
are no longer suitable for switching low level loads.
