Coils for OTZT_ and OTZM_ electrical interlocks
By installing a coil inside the housing of the interlock kit the switch can be interlocked elec-
trically in the OFF-position or both in the OFF- and ON-positions. The electrical interlock
works using the “closed circuit principle”, meaning that when the control voltage is not con-
nected to the coil, the switches provided with A-type interlocks cannot be turned to the
ON-position and switches with L-type interlocks cannot be turned to the ON- or OFF- posi-
tions.
