Environmentally-friendly tilt switch. 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 ammonia-resistant materials. Totally sealed body allows process compatibility for time- and money-saving automatic soldering and cleaning. Space-saving compact dimensions allow high density mounting. Internal steel ball movement allows functionality of 360° circumference rotation. 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.
