www.nkk.com K IndicatorsAccessoriesSupplement Tactiles KeylocksRotaries PushbuttonsIlluminated PBSlides Programmable RockersTouch Tilt Toggles 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. DSB 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 DSA Actual Sizes Distinctive Characteristics
