Abstract
An electrical switch for use in an electrical actuation system is provided including a switch box having an upper surface with an opening. A stem guide is coupled to the switch box adjacent the opening. A lock out mechanism is received within a central bore of the stem guide and the opening. The lock out mechanism is configured to move between a first position and a second position to selectively break a flow of power through the electrical switch. A pin is configured to couple the lock out mechanism to the stem guide in one of the first position or the second position.

An electrical switch for use in an electrical actuation system comprising:
- a switch box having an upper surface with an opening;
- a stem guide coupled to the switch box adjacent the opening;
- a lock out mechanism received within a central bore of the stem guide and the opening configured to move between a first position and a second position to selectively break a flow of power through the electrical switch;
- and
- a pin configured to couple the lock out mechanism to the stem guide in one of the first position or the second position, such that when the pin is removably installed into the lock out mechanism, the lock out mechanism is not movable between the first position and the second position.
An electrical actuation system of an aircraft comprising:
- a power feed line configured to supply power to at least one downstream component;
- and
- an electrical switch arranged along a portion of the power feed line including:
- a switch box having an upper surface with an opening;
- a stem guide coupled to the switch box adjacent the opening;
- a lock out mechanism received within a central bore of the stem guide and the opening configured to move between a first position and a second position to selectively break a flow of power through the power feed line;
- and
- a pin configured to couple the lock out mechanism to the stem guide in one of the first position or the second position such that when the pin is removably installed into the lock out mechanism, the lock out mechanism is not movable between the first position and the second position.
