The headlamp switch has a built in circuit breaker and if the headlamp system has excessive amp draw it will cause the circuit breaker in the headlight switch to cycle on and off. When you replaced the burnt switch did you have a look at the connector to see if it was also burnt. If not have a look at the connector and if there are signs of it having overheated and melted then you need to also replace it. If its been over heated it will cause a loose connection which can cause an excessive amp draw.
