Basic Models
General-purpose
• A variety of actuators is available for a wide range of application. • The contact mechanism of models for micro loads is a crossbar
type with gold-alloy contacts, which ensures highly reliable operations for micro loads. • Contact Gap:
H2: 0.20 mm (extra-high-sensitivity) H: 0.25 mm (high-sensitivity, micro voltage current load) G: 0.5 mm (standard) E: 1.8 mm (high-capacity)
Drip-proof
• These Switches use a rubber boot on the actuator and adhesive fill between the case and cover to increase resistance to drips.
• Models with drip-proof terminal protective covers and molded terminals with resin filling are also available.
Split-contact Models
• This type is identical in construction to the general-purpose basic switch except that it has two pairs of simultaneous acting contacts by splitting moving contacts.
• Since the moving contacts are connected to a common terminal, either parallel or series connection is possible.
• Highly reliable micro load switching is ensured if the model is used as a twin-contact switch.
Maintained-contact Models
• The maintained-contact type has a reset button at the bottom of the switch case, in addition to the pushbutton (plunger) located on the opposite side of the reset button. Use these buttons alternately.
• Since the Switch has greater pretravel than overtravel, it is suitable for use in reversible control circuits, manual reset circuits, safety limit circuits, and other circuits which are not preferable for automatic resetting. (For further details, refer to individual datasheets.)
