PURPOSE:To enable the control of a channel select in the electronic tuning tuner of a controller for remote operation, by means of combining a multi-step multi contact and a rotary switch with single multi-contacts of an endless structure. CONSTITUTION:A controller RC for remote operation is composed of two rotary switches. a rotary switch 2 has a plurality of needles 2a-2e which are connected to a plurality of electric circuits and fixed contacts A-B by which these needles connect the different connection with said circuits. A rotary switch 3 has a single needle 3a corresponding to a plurality of fixes contacts F-J which contacts to the fixed contacts A-E respectively, and the switch enables one of said plural electric circuit to be changed over and connected to other electric circuit selectively by means of connecting this needle 3a to other circuit. |
