This example describes the multi-place control switch, you can use multi-button switch control one route electrical appliances (eg lights). It applies to hotels, hospitals, corridors, staircases and other more than 3-way switch controlling situation. The circuitis composed ofthe power supply circuit, monostable, bistable trigger, and buttons S1 ~ Sn, thyristor VT etc.Components select.R1 selects 1/2W carbon film resistors or metal film resistors; R2 ~ R4 select 1/4W carbon film resistors. C1 selects polyester capacitor or CBB capacitor with withstand voltage being greater than 400V; C2 uses 25V electrolytic capacitor; C3 uses monolithic capacitors or polyester capacitors. VD selects 1N4007 silicon rectifier diode. VS selects 1/2W, 9V voltage silicon diode. VT selects 3A, 600V bi-directional thyristor. IC selects CD4013 or C043 dual D flip-flop integrated circuits. S1 ~ Sn select normally open buttons.
