PURPOSE:To suppress load to be applied on a power supply instantaneously by avoiding concurrent switching operation of a plurality of switches. CONSTITUTION:In a switching system comprising N switches 1 each having switches 305, 306 for automatically interrupting switching control input signal and N switching circuits 301 each having a switch 307 for outputting a switching state signal of the switch 1, connection is made such that a switching state signal of (i-1)th Switch(N>=i>2) is passed as an i-th switching control input concerning to switches 302, 303 for inputting a switching control signal to a first switch and second to N-th switches. Consequently, switching operation of N switches is transmitted sequentially to following switch thus avoiding concurrent switching operation of all switches. |
