Abstract
PURPOSE: To add a required number of control boxes when units under time limit control are initially small in number and will be more installed later on, by making a main switching part separate from and independent of a timer body by control boxes.
CONSTITUTION: Into a receptacle on a wall, etc., (b) and (d) of plug P of control box 3 are inserted and to (a) and (c) of receptacle R, the power plug of controlled unit 2 are connected. A time limit signal, sent out from controller 12 to output circuit 13 of timer unit 1 is inputted to the base of transistor Tr in this output circuit 13, so that this Tr will conduct. Once Tr conducts, relay S is excited by direct-current power supply E via output lead 16 and control line 18 to make its contact (s), causing conduction between (a) and (b). As a result, controlled unit 2 is applied with power.
