PCB Processing
Soldering: Wave Soldering Recommended: See Profile A in Supplement section.
Manual Soldering: See Profile B in Supplement section.
Cleaning: These devices are not process sealed. Hand clean locally using alcohol based solution.
Standards & Certifications
Flammability Standards: Actuator and lower case of glass fiber reinforced polyester and case of glass fiber reinforced polyamide UL94V-0
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.

Distinctive Characteristics
Pushbuttons
Very compact dimensions allow for high density, side-by-side or
end-to-end mounting within tight dimensional applications.
Programmable Illuminated PB
Detent mechanism provides positive actuation to indicate
circuit status.
Twin sliding contact mechanism with self-cleaning action
provides smooth actuation and produces high contact reliability.
Keylocks
Visible indication of position by spot on top of red actuator
and through window on side.
