Current values have been assessed on the basis that each mechanism is used to switch only one load, either on it's normally-open
or normally-closed contacts. When two circuits per mechanism are switched the same current values on AC may be used but on
resistive and inductive DC loads the smaller values shown in brackets should be used.

Note: Place ‘S’ for Silver Plated and ‘G’ for Gold Plated terminals in bracket ‘( )’ against Ordering Code of Micro Switch.

All dimensions are in mm.
