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: ba-
sic, split-contact, maintained-contact, and adjustable contact
gap types.
• A series of standard models for micro loads is available.
• A series of molded terminal-type models incorporating safety
terminal protective cover is available.

■Configuration
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:
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.)

F-170 General-purpose Basic Switch Z
Note: 1. Do not use the M12 mounting screw and the case mounting hole at the same time, or excessive pulling force will be imposed on the
Switch and the case and cover may be damaged.
2. On the model Z-15GQ3-B, PT can be set to a value larger than that for the Z-15GQ.
3. On the model Z-15GQ8-B, operating position can be adjusted by providing a screw in the plunger section.
The M3 hole with a depth of 10 mm is a through hole. Take precautions so that no water or screw lock agent penetrates into the hole.
Note: Do not use the M12 mounting screw and the case mounting hole at the same time, or the case may be damaged.

Reverse Hinge Lever
Note: The pin plungers of reverse-type models are continuously pressed by the actuator levers with compression coil springs and the pin plungers
are freed by operating the levers. Reverse-type models are highly vibration- and shock-resistive because the pin plungers are normally
pressed.
