DS Tilt Switches

Contactless Tilt Switch
Series DS
Distinctive Characteristics
Photo interrupter, rather than contacts, ensures high reliability.
Sealed construction for protection from environmental elements, including hydrogen sulfide,
sulfur dioxide, and nitrogen hydroxide.
Terminals are made of ammonia-resistent
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 DS 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°
in any direction.
