Polarized latching relay, with position display and switch for manual operation
Using the H-armature principle the polarised latching relays are noted for their high resistance to shocks and vibrations. They are always in a defined switching-posi- tion and therefore there is no loss of information in case of power failure. The advantage of polarised latching relays is the pulse driven operation of some milliseconds, coil heating can be neglected. Relay can also be set by manual operation.
The relays are designed and manufactured in accordance to international Standards of IEC 61810 part 1.
