ABSTRACT:
An operator (10) having a lock releasing key (10a) formed thereon is removably coupled to a pivoted actuator (6) by resilient tabs (10d) depending from the operator which are cammed outwardly over the actuator during coupling operation and which engage with undercut surfaces (6e) in the actuator when the operator is fully seated upon the actuator. The tabs (10d) seated at one end of the actuator align with formations (4e) in the housing (2, 4) in the ON position of the actuator to prevent outward camming movement of the respective tabs, thereby preventing removal of the operator in the ON position.
