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