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 po...
