The SM series devices have not been tested for UL recognition and CSA certification.
These switches are designed for use in a low-voltage, low-current circuit.
When used as intended in a low-voltage, low-current circuit, the results do not produce
hazardous energy.

Visible indication of position by spot on top of red actuator
and through window on side.
Twin sliding contact mechanism with self-cleaning action
provides smooth actuation and produces high contact reliability.
.100” x .100” (2.54mm x .2.54mm) center-to-center inch terminal
spacing allows standard PC board mounting in side-by-side or
end-to-end arrangements.
Insert molded terminals lock out flux, solvents, and other contaminants.
