<p>An electric switch arrangement has two connection terminals (4, 5) on a body housing mechanical and electrical components assembled to provide "Off" (2) -"Low" (3) - "High" (1) control positions to control the energy delivered to an electrical load (L), such as a lamp, operating from an alternating current source (S) by way of said terminals, the "Low" control being provided by means of a half wave rectifier. D1 which may be mounted in the body of the switch as in Figure 3 (not shown). <IMAGE></p> |
