Datasheet
Illuminated Flush Mount Electro-Mechanical Push Buttons
• Rugged design; easy installation with no assembly or individual
wiring required
• Push-to-stop, twist-to-release (all models), or pull-to-release
(standard and large) operation per IEC60947-5-5
• Latching design complies with ISO 13850; direct (positive) opening
operation per IEC 60947-5-1
• Compliant with ANSI B11.19, ANSI NFPA79, and IEC/EN 60204-1
Emergency Stop requirements
• “Safe Break Action” ensures N.C. contacts will open if the contact
block is separated from the actuator
• 8-pin M12/Euro-style Quick Disconnect; 1/2-in NPT port on
terminal strip models (cable-gland included)
• Models with highly visible indication of actuation (armed or
depressed/latched button)
• "Emergency Stop" legend included
Models SSA-EB… series are "mushroom-style" electro-mechanical emergency stop push buttons. When the button is
armed, the switch's safety contacts (N.C.) are closed and its monitoring contacts (N.O.), if present, are open. When the
button is pushed, the switch's safety contacts open and the monitoring contacts close. The contacts remain in this
condition until the push button is manually rearmed by twisting clockwise the red push button actuator, or by pulling on
the models with the standard actuator. The SSA-EB1(2)..-..ED1.. series has a flat mounting base for ease of mounting
without requiring an additional enclosure.
The EZ-LIGHT® illumination logic allows for easy identification of a pushed/actuated button. An armed button will light a
steady yellow or green illumination or OFF (depending on model), a pushed/actuated button is indicated by a red
illumination (flashing or solid depending on model). An optional input allows an armed button to illuminate a steady red to
indicate a machine stop or emergency stop condition. In a series string of E-Stop buttons, this logic gives the user the
choice to either have the armed buttons stay YELLOW (GREEN) or turn steady RED when a STOP condition exists.
SSA-EB1M… series padlock-style lockable emergency stop push buttons are intended to prevent unauthorized or accidental
resetting of a pushed/latched button. The SSA-EB1M… series are not to be used as an energy isolating device or as the
sole means of complying with Lockout/Tagout or with the requirements of the isolation of hazardous energy (see OSHA
29CFR1910.147, ANSI Z244.1, CSA Z460, ISO 14118). The locking feature can be used to provide supervisory/personal
control and provide an additional safety measure(s) to reduce the likelihood of inadvertent arming and energization of the
emergency stop circuit.
