Estoy con un programa de encuestas de satisfacción de usuarios. Pongo un par de contextos:

"The best way to ensure a high participation rate in the survey is to award prizes. Below you can add your custom prize text to the survey invitation sent out to the guests. ***Turn on the switch*** below to add a custom prize text to your survey invitation."

"Each element below represents a question or a group of questions concerning a specific topic within the questionnaire. By ***turning the switches on***, the questions will be activated within the questionnaire. To see the specific questions concerning the functions and staff click here. Please ***turn the switches on/off*** for each element to reflect the conditions within your club.

No sé si en el contexto de una página web se traduce literalmente como "encender/apagar el interruptor" o si se dice de otra manera en español.
