The utility model belongs to the field of travel switches, discloses a travel switch for an electric precipitation blanking valve of a thermal generator set, and aims to solve the problems that the conventional electric precipitation blanking valve is mostly a mechanical travel switch, the switch acts by means of contact collision with a crank arm, and the mechanical travel switch is damaged if the crank arm deviates too much. In order to solve the problems that an electric dust removal blanking valve is often jammed, the switch positions are inconsistent each time, the change is large, the adjustment allowance of a mechanical travel switch is insufficient, and the requirements cannot be completely met, the technical scheme of the utility model is as follows: the electric dust removal blanking valve comprises a box body, and the box body is internally provided with an angle sensor, a microcontroller, two relay output circuits, two positioning keys, a dead zone key and three indicator lamps; according to the u
