Best-selling Basic Switch Boasting High

Precision and Wide Variety

• A large switching capacity of 15 A with high repeat accuracy.

• A wide range of variations in contact form for your selection:

basic, split-contact and maintained-contact.

• A series of standard models for micro loads is available.

• A series of molded terminal-type models incorporating

safety terminal protective cover is available.

Model Number Structure

Available types

• 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)

F:

1.0 mm (split-contact models)

• 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.

• 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.

• 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.)
