Description
General Notes
Series 04, a modular switching system, offers users a wide range of
possible combinations. A broad variety of actuators is available,
round or square in shape, for use as pushbuttons, illuminated push-
buttons, keylock switches or lever-operated switches, and indicators.
Other special actuators, such as mushroom heads or emergency
stop switches and buzzers can also be supplied.
Configuration
Max. 3 switching elements, as snap-action or slow-make switches,
can be clipped as modules to each actuator. Each switching element
is equipped with 1 or 2 independent switching system with normally
closed or normally open contact. The standard contact material is
hard silver.
Mounting
The Series 04 standard pushbuttons are mounted in a 22,5 mm dia.
cut-out. Flush mounted pushbuttons are mounted in a 30,5 mm dia
cut-out.
Terminals
The switching elements and the lamp blocks can be supplied with
screw or plug-in terminals.
Lenses
Lenses of transparent plastic or aluminium are available in various
standard colours.
Marking
For engravings, hot stamping, film inserts with standard legends or
symbols, see page 143.
Illumination
Illuminated pushbuttons or indicators can be supplied with lamps Ba
9s (6-130 V), Multi-LED lamps Ba 9s (6, 15, 24, 48 V) or with neon
lamps Ba 9s.
Position indicating
When a switch with maintained action is actuated, the lens remains
in the depressed position mechanically. The state of the switch is ap-
parent at all times from the position of the lens
Keylock switch
Standard lock No. = 251 with ending of part No. 0 (example
704.335.0). Following lock No. also available (lock No./ending of part
No.) 252/1, 253/2, 254/3, 255/4, 256/5, 257/6, 259/8, 260/9.
2 keys will be delivered per keylock switch.
All dimensions in mm.
We reserve the right to modify technical data.
Rotary switch
The rotary switches of Series 04 are ideal control and instrument
switches. The switch types (CG4-1) are suitable special for switch for
small voltages. They comply with the rules IEC 947-3 and VDE 0660,
part 107.
The axial arrangement of the connector block gives the opportiunity
to mount the switches side-by-side or next to the cable duct. The con-
tact marking remains legible in mounted situation too.
The required space of this switch is very small.
