Tilt Switch Series DS Distinctive Characteristics DSA Environmentally friendly, contains no mercury. High contact reliability due to sealed body. The switch is triggered when tilted beyond 10 of the horizontal. PCB adaptor available as an accessory. DSB Photo interrupter, rather than contacts, ensures high reliability. 1 million operations minimum. Sealed construction for protection from environmental elements, including hydrogen sulfide, sulfur dioxide, and nitrogen hydroxide. Terminals are made of Actual Sizes ammonia-resistant materials. Totally sealed body allows process compatibility for time- and money-saving automatic soldering and cleaning. K Space-saving compact dimensions allow high density mounting. Internal steel ball movement allows functionality of 360 circumference rotation. DSA The DSB series switch is well-suited to meet product safety concerns due to normally closed (on) status. Crimped terminals ensure secure mounting and prevent dislodging during wave soldering. The switch is triggered when tilted beyond 30 of the horizontal.
