Alternating Relay Switch Circuit

This is a simple design circuit for relay that can be utilized to drive a mono stable relay, using a single button switch. The main purpose is to show that we can toggle an output state electronically, although physically you use only a push button switch. This is the figure of the circuit.


When I press the button IC output (pin 3) assumes the high level, but Q1 transistor switches off. So when I release the button the relay is energized (now the exchange switch is closed on 5 and 9). When I press the button again IC output assumes the low level, but Q3 transistor switches on: when I release the button the circuit goes to the start condition.
