Abstract

A dual function air-gap switch actuator (26) is incorporated into the generally planar face of a wall box dimmer. The switch actuator is finger operated and provides both a main power disconnect via air-gap contacts (211) and the means (212) to activate a secondary function. The dual function air-gap switch actuator is optionally fitted with an indicator lamp (265).
