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)
F:
1.0 mm (split-contact models)
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.)
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.

are freed by operating the levers. Reverse-type models are highly vibration- and shock-resistive because the pin plungers are normally
pressed.
