Features
• An auxiliary contact can be added just by a single press.
• An auxiliary contact can be added to the front mounting unit
without changing the mounting area. This is conducive to the
miniaturization of the control panel.
• Using bifurcated contacts with high reliability of contact so
that it can operate normally with minimum operating voltage
and current (DC5V, 3mA) (SZ1FA11, SZ-A-C, SZ-AS1-C )
