Structure and Nomenclature
Structure
Direct Opening Mechanism
1NC/1NO Contact (Slow-action)
Conforms to EN60947-5-1 Direct Opening Operation
(Only the NC contact side has a direct opening
mechanism.)
When contact welding occurs, the contacts are
separated from each other by the plunger being
pushed in.
Contact spring
Return spring
Built-in Switch
The built-in switch has a direct opening mechanism
that forcibly separates the NC contact even when
there is contact deposit.
Cover
The cover, with a hinge on its lower part, can
be opened by removing the screw of the
cover, which ensures ease of maintenance
and wiring.
Safety-oriented Lever Setting
(Form-lock construction)
Grooves which engage the lever are cut in the lever and
rotary shaft to prevent the lever from slipping against the
rotary shaft.
There are resin-lever and metal-lever types.
Fixed contact (NC)
Movable contact
Fixed contact (NO)
Plunger
2NC Contact (Slow-action)
Conforms to EN60947-5-1 Direct Opening Operation
(Both NC contacts have a direct opening
mechanism.)
When contact welding occurs, the contacts are
separated from each other by the plunger being
pushed in.
Contact spring
Return spring
Head
The direction of the switch head can be varied to any of
the four directions. (Roller plunger models can be
mounted in either of two directions at a 90° angle.)
Note: M12 connector types are not available for
Conduit Opening
A wide variety of conduits is available.
