Most housings are made of 304 stainless steel, featuring wear resistance and an attractive appearance; some pins are brass with silver plating for better conductivity. The common waterproof rating is IP67, achieving dust and water protection through sealing rings.
Internal contacts are available in three types: normally open (NO), normally closed (NC), and common terminal (COM); some models come with LED lights (polarity-sensitive). Pins are offered in 5-pin, 6-pin, etc., supporting latching or momentary functions. Custom connectors are available for easy wiring on select models.
Mounting diameter ranges from 8-30mm (panel cutout must be matched, e.g., 16mm, 22mm).
