Abstract
A first electronic apparatus is provided with a relay energized at a low voltage, the relay having a contact connected in parallel with a power supply switch for the first electronic apparatus. The first electronic apparatus is further provided with a signal generator circuit for energizing a second electronic apparatus. An output signal generated from a third signal generator circuit of a third electronic apparatus is applied to the coil of the relay of the first electronic apparatus thereby to operatively interlock the first electronic apparatus with the third electronic apparatus. Alternatively, an output signal generated from a signal generator circuit of the first electronic apparatus is applied to a relay of the second electronic apparatus having a contact through which power is supplied to the second electronic apparatus, thereby operatively interlocking the second electronic apparatus with the first electronic apparatus.
