*Measured above reference line. Refer to dimensional drawing above.
**Operating Forces listed above are for E78/E79 switches only. E75 Operating Force: 921 grams max. for momentary switches.
†Dual function switch: Push in to operate in normal momentary mode and pull out for maintained action.
  Circuitry

Double throw (DPDT) and single throw normally opened or normally closed (DPST NO and DPST NC) versions are available.

To order DPDT, use "0" before the final "A" in part number.
For DPST NO, use "1"; for DPST NC use "2".

Example:
E78–30A = DPDT
E78–31A = DPST NO
E78–32A = DPST NC

  Ordering Information

Select the current rating you need.
Combine the corresponding Series/Prefix number with the appropriate suffix number
for the actuator type and circuitry you require.
(Switch prefix for VDE approved switches must be “F”)

Example:
E75–00A = 16A, with basic momentary action actuator, DPDT
E78–21A = 0.1A, with push-pull (reset) actuator, DPST NO
F79–32A = 10A, VDE approved/International version, with dual action actuator, DPST NC
