EAO Switch
Sealed actuator (IP 67, similar to NEMA 4 and 13)
Series 92 sealed actuators are used whenever an
attractive, flush-mount, sealed switch or indicator is
needed. They find particular application in hostile environments
where rugged dependability is important.
Typical applications include instrumentation, industrial
equipment, security devices, and food service equipment.
Sealed units can often be used in place of expensive,
complex membrane switch systems
Standard Actuator (IP 40, similar to NEMA 5)
Series 92 standard actuators are dependable, brightly
lighted, general purpose, flush-mount switches. They are
used in non-critical environmental conditions where IP 40
protection is adequate.
Interchangeability with Series 84 components
Series 92 actuators can be used with Series 84 switching
elements . Also, award-winning Series 84 flush mount pushbutton
actuators are designed to be used with Series 92 PCB
mounted switch elements.
Mounting the Series 92
- Pushbutton actuators and indicators with sealed (IP 67)
membrane-type lenses or with standard (IP 40) lenses fit in a 16
mm hole and are secured to the front panel with a mounting nut.
- The switch elements are installed on the printed circuit board
according to the PC board layout.
- Mounting flanges are attached to the PCB with two screws
and are only used where needed tor support. The mounting
array indicates the suggested placement of flanges.
- The actuators simply snap into the mounting flanges to assure
a secure connection between panel and PCB. The actuator
geometry determines that a constant 12 mm (0.473 in.) space is
maintained between the front of the panel and the printed circuit
board. This distance is maintained with or without the mounting
flange. If only a few switches are to be mounted on a large PCB,
a spacer is available to provide additional support.
Series 92 Ordering Procedure
First order actuator or indicator from table below indicating lens color. Then select switch element or indicator socket, LED or incandescent lamp, and mounting flange (if needed) separately.

Series 92 PCB Support System
The EAO Series 92 switching system incorporates a unique
technique for spacing and supporting the printed circuit board.
- Pushbutton actuators and indicator housings attach to the
front panel in a 16 mm hole.
- Switch elements and/or indicator sockets solder to the PCB.
- Mounting flanges are attached with two screws to the PCB
and the entire assembly functions as a stand-off for support and
spacing. See "Mounting Information" for suggested positioning of
mounting flanges.
- The PCB is supported and spaced from the panel front
surface at a constant distance of 12 mm (0.473").
- For areas on a large PCB where no switches or indicators are
mounted but support is needed, EAO has developed a patented,
adjustable spacer. The spacer is inserted into a special mount-
ing flange which automatically compensates for panel thickness.
(See drawing below) The spacer is first attached to the rear of
the panel by removing a protective foil which exposes a special
high strength adhesive surface. There are four flexible ears on
the spacer which prevent the adhesive from contacting the
surface. When the PCB is mated with the panel containing
switches and indicators, a firm push on the spacer will flex the
ears aside and the adhesive will bond to the panel surface. The
special mounting flange has insertion steps of 1.5, 2, 2.5, 3, 3.5,
and 4 mm which enable the PCB to maintain a constant 12 mm
distance from the front panel.
- Do not fully tighten the screws which attach the mounting
flanges to the PCB until the circuit board and the panel are
assembled together. This aids in aligning the components.
- The PCB can easily be removed by removing the screws
which hold the mounting flange to the PCB.
