What to do if sparks appear when the bathroom heater switch is turned off

Usually, this is caused by poor contact. If the sparks are very obvious, you will need to replace the bathroom heater switch with a new one.

If the lamp tube is burnt out, you will need to go to a hardware store to purchase a lamp tube of the same model and install it to solve the problem.
