Quick-replacement contact blocks and transformer units

The snap-on construction makes replacement and addition of contact blocks and transformer units very simple and straightforward.

Oil-and dust-proof operator module construction

The protection level of the AM22/DM22 operator modules conforms to IEC Standard IP65. The special seals protect the operator modules and switch mechanisms against oil, dust, and grime, thus ensuring high performance in dusty and moist environments.


  • Pushbutton and selector switches with1NO+1NC: 40mm deep
    Pilot lights: 35mm deep
  • The transformer now occupies far less space.

Self-cleaning contacts

All the contacts are double break type and feature self-cleaning action.
Every time the switch is operated, the contact surfaces are wiped with asliding movement, thus ensuring high contact reliability even at low voltage and small current levels (5V, 5mA).

Metal nut

Safer model with metal nut is also available


  • Wiring from two directions is possible.
  • Wiring in both vertical and lateral directions facilitates wiring in narrow spaces.
  • Color coding of contact blocks makes wiring easy.
    1NO: Blue, 1NC: Red
    Lamp terminal and transformer unit: Black


  • A terminal cover is provided, assuring safety and security.
  • FUJI’s original Trigger Action mechanism is used in the emergency stop pushbuttons. They are suitablefor emergency stop and safety. This mechanism prevents the contacts from moving until the button is pushed and locked.


  • Excellent oil-tight construction (IP65) of the operator.
  • Closure of the contact block has been improved.
