Datasheet
Compact size - only 27.9 mm deep behind the panel. Reliable “Safe break action.”
• The depth behind the panel is only 27.9 mm for 1 to 4 con tacts, both 
on illuminated and non-illuminated.
• IDEC’s original “Safe break action” ensures that the contacts open 
when the contact block is detached from the operator.
• 1 to 4NC main contacts and 1NO monitor contact
• Push-to-lock, Pull or Turn-to-reset operator
• Direct opening action mechanism (IEC 60947-5-5, 5.2, IEC60947-5-
1, Annex K)
• Safety lock mechanism (IEC 60947-5-5, 6.2)
• Degree of protection IP65 (IEC 60529)
• Silver with gold contacts.
• Two operator sizes: ø29 and ø40 mm
• Dark red (Munsell 5R4/12) or bright red (Munsell 7.5R4.5/14) colors 
are available for the operator of non-illuminated emer gency stop 
switches.

• Minimum applicable load: 5V AC/DC, 1 mA (reference value) 
(Operating area may vary according to the operating conditions and load 
types.)
• The rated operating currents are measured at resistive/inductive load types 
specied in IEC 60947-5-1.
