• Direct opening mechanism to open the circuit when the contact
welds → .
• Safety lock mechanism prevents operating errors.
• Easy mounting and removal of Switch Blocks using a lever.
• Mount three Switch Units in series to improve wiring efficiency
(with non-lighted Switch Units, three Units can be mounted for
multiple contacts).
• Finger protection mechanism on Switch Unit provided as a
standard feature.
• Install using either round, or forked crimp terminals.
• Oil-resistant to IP65 (non-lighted models)/IP65 (lighted models)
Note: Be sure to read the precautions for all pushbutton switches in the
Pushbutton Switches Group Catalog (Cat. No. X018), as well as
the “Safety Precautions” on page 19.

This Switch enables emergency stops only when the pushbutton is
pressed intentionally and firmly.
Even if an object or person touches the pushbutton by mistake, the
contact will not be released unless the pushbutton reaches the lock
position.
This Switch uses a finger protection
mechanism to prevent electrical shocks.
Moreover, it is provided with a mechanism
to prevent terminal screws from coming
off and also allows connection to either
round or forked crimp terminals.

Safety Precautions
Be sure to read the precautions for all pushbutton switches in the Pushbutton Switches Group Catalog (Cat. No. X018).
Using the Microload
Do not apply a voltage exceeding the rated voltage across the
incandescent lamp terminals.
The lamp may be destroyed and the operation unit may fly out.
■ Precautions for Correct Use
Mounting
• Always make sure that the power is turned OFF before wiring the
Switch. Also, do not touch the terminals or other current-carrying
ports while power is being supplied. Electric shock may occur.
• Do not tighten the mounting ring more than necessary using tools
such as pointed-nose pliers. Doing so will damage the mounting
ring. The tightening torque is 0.98 to 1.96 N·m.
• Recommended panel thickness: 1 to 5 mm.
• Contact failure may occur if a Switch designed for a standard load
is used to switch a microload. Use Switches within the application
ranges shown in the following graph. Even within the application
range, insert a contact protection circuit, if necessary, to prevent
the reduction of life expectancy due to extreme wear on the
contacts caused by loads where inrush current occurs when the
contact is opened and closed.
The minimum applicable load is the N-level reference value. This
value indicates the malfunction reference level for the reliability
level of 60% (O 60) (conforming to JIS C5003).
The equation, O 60 = 0.5 x 106/time indicates that the estimated
malfunction rate is less than 1/2,000,000 with a reliability level of
60%.

• When DC-specific LEDs are used, wire the Switch so that the X1
terminal is positive.
• Terminal screws must be Phillips or slotted M3.5 screws with a
square washer.
• The tightening torque is 1.08 to 1.27 N·m.
• Single wires, stranded wires, and crimp terminals can be
connected to the Switch.
• Applicable Wiring Materials:

Others
• If the panel is to be coated, make sure that the panel meets the
specified dimensions after coating.
• Due to the structure of the Switch, severe shock or vibration may
cause malfunctions or damage to the Switch. Also, most Switches
are made from resin and will be damaged if they come into contact
with sharp objects. Particularly scratches on the Operation Unit
may create visual and operational obtrusions. Handle the Switches
with care, and do not throw or drop them.
20.2 mm max.
• After wiring the Switch, maintain an appropriate clearance and
creepage distance.
Do not allow the
Switch to drop and hit
the floor.
Operating Environment
• The IP65 model is designed with a protective structure so that it will
not sustain damage if it is subjected to water from any direction to
the front of the panel.
LEDs
• The LED current-limiting resistor is built-in, so internal resistance is
not required.
• If commercially available LEDs are used, select the ones that meet
the following conditions:
Base: BA9S/[email protected]
Overall length: 26 mm max.
Power consumption: 2.6 W max.
Do not place or drop
heavy objects on the
Switch.
Do not operate the
Switch with hard or
sharp objects.
