EAO Switch

Series 92
Panel-mounted PCB Pushbutton Switches and Indicators

SPST contacts rated at 42 V, 50 mA
More than 1,000,000 operations
Replace complex membrane switch systems
Standard (IP 40) and sealed (IP 67) actuators
Excellent tactile feel
Actuators mount in standard 16 mm front panel hole
LED in single or multi-chip and bi-color

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 Flange


Choose the number of mounting flanges needed to secure the printed circuit board. Contact Beckwith Electronics for recommended mounting flange spacing. There is a spacer available to be used where additional support is required. When removing flange, remove PCB fastening screws and use tool 92-971.0 to dismantle mounting flange from actuator.

Contact Beckwith Electronics for Series 92 engraved legends.

Assembled Printed Circuit Board Assembly for Pushbuttons & Indicators

Series 92 PCB Support System

    The EAO Series 92 switching system incorporates a unique technique for spacing and supporting the printed circuit board.
  1. Pushbutton actuators and indicator housings attach to the front panel in a 16 mm hole.
  2. Switch elements and/or indicator sockets solder to the PCB.
  3. 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.
  4. The PCB is supported and spaced from the panel front surface at a constant distance of 12 mm (0.473").
  5. 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.
  6. 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.
  7. The PCB can easily be removed by removing the screws which hold the mounting flange to the PCB.
