Claim 14:
15. An emergency stop switch, comprising:
a housing having a sidewall comprising an optical indicator portion having an externally visible annular illumination surface substantially surrounding, and facing away from, a longitudinal axis;
an internal circuit enclosed in the housing and adapted to illuminate the externally visible annular illumination surface; and
a switching module comprising a push-button actuator adapted to be manually actuated to move relative to the housing along the longitudinal axis between an armed position and an actuated position, and a plurality of pairs of electrical contacts enclosed in the housing, each pair switchable between a conducting state and a non-conducting state, the push-button actuator being adapted to switch each one of the plurality of pairs of contacts between the conducting and non-conducting states when the push-button actuator is moved from the armed position to the actuated position,
at least one of the plurality of pairs of contacts of the switching module being connectable to one or more external circuits, the switching module being adapted to connect electrical power to the one or more external circuits when the actuator is manually moved to the armed position, and to interrupt electrical power to the one or more circuits when the actuator is manually moved to the actuated position,
at least another one of plurality of pairs of contact of the switching module being connected to the internal circuit and adapted to cause the internal circuit to output light of different colors through the annular illumination surface depending on the longitudinal position of the push-button actuator.
