Non-Illuminated Selector Switch 30mm
This Siemens 52SA2BDB is a non-illuminated selector switch operator designed for 30 mm panel cut-outs. It provides three lever positions with a momentary, maintained, momentary action sequence. The operator is black and uses a Cam B contact configuration. It carries CSA certification and UL listing for industrial control panels.
NEMA 1 3 4 4X 12 13 Environmental Rating
The switch operator is rated for NEMA types 1, 3, 3R, 4, 4X, 12 and 13 enclosures. This covers indoor use, falling dirt, rain, sleet, windblown dust, splashing water, hose-directed water, corrosion, oil and coolant seepage. No IP rating is assigned to this operator. Buyers needing a specific IP code should verify enclosure compatibility separately.
Three-Position Lever Momentary Maintained Momentary
The defining specification is the three-position lever action: momentary in the left and right positions, maintained in the centre. This suits applications requiring spring-return from two directions with a latched middle state. It is not suitable for two-position maintained switching or key-operated security requirements.
