On Off switch electronic project

An on off switch with a single button can be designed using electronic diagram below. Schmitt trigger output toggles N1 when the switch is closed briefly. This operation is achieved with a chassis that simple circuit because the input trigger threshold levels are maintained between tipping. If the trigger output is logic "1" logic, the capacitor C1 will charge through R1. When switch S1 is closed, the entry will be passed in the state trigger logic "1" and output will be "0" logic.
For this circuit can be used several types of triggers Schmitt: 4093, 4016, 74LS14, 74LS132. When using TTL integrated circuits, voltage must be 5 V ± 0.25 V CMOS integrated circuit, it must be between 5 V and 15 V.
