Control and Signalling devices Ø 22.5
This range of Ø 22.5 push buttons, selector switches, illuminated switches, illuminated selector switches and pilot lights have been
designed to provide the following salient features:
• Economy of space • Aesthetically pleasing
• Self Wiping Contact • Heavy duty construction
• Safe in operation • Shrouded terminals
• Simple to mount (screw driver is all that is required) • Very good flame resistance
• Fixing method unaffected by excessive vibration-unit • Use of LEDs for long life and minimum
does not rotate maintenance
• Protection against electric shock (unit grounded)
Actuators
The circular actuators have chrome plated metal bezels, and are interchangeable on the different types of contact elements.
Contact Elements
The contact elements are double break and have self wiping contacts. The elements are
interchangeable and can be stacked without additional hardware. 1 to 6 elements (NO or NC)
can be used with non illuminated actuators, whereas, 1 to 4 elements (NO or NC) can be used
for illuminated actuators. Gold plated NO and NC contact elements for low voltage, low
current switching circuits < 25 mA, are available.
LED Illuminated Actuators and Pilot Lights
LED illuminated actuators & pilot lights are supplied, LED in bayonet cap suitable for
operating at various voltages. LED bulbs with bayonet cap are constructed in the standard
BA9S design with OAL max. 28 mm.
Terminals
Contact elements and pilot lights are designed to have shrouded terminals with
combination flat/phillip screws.
Fixing
The control devices Ø 22.5 can be fixed in any position on panels of 1 to 6 mm (.039 -
.236 in.) thickness. We recommend minimum fixing centers of 30 x 40 mm (1.2 x 1.57”).
However, the dimensions and configuration should be decided on the basis of the
application. The actuators and the lens assemblies lock on to the holding bracket using
a bayonet type of fixing which enables a simple and fast assembly. The complete
assembly is locked into position on the panel by two M4 pointed screws on the bracket,
tightened equally from the rear. The screws should be tightened adequately to such an
extent as to pierce through the paint on the panel from inside. These screws also
ensure the grounding of the unit.
