• the base of the starter consists of a base on which are fixed two legs that allow to establish contact.
• the socket for fixing the starter consists of two semicircular grooves for locking the legs, or to release them by a simple rotation.
• the choke or ballast is used to ionize the gas contained in the tube so as to obtain a breakdown voltage thereof by sending a voltage of between 700 and 800 volts. Once the breakdown voltage obtained, the neon ignites and maintaining in this state requires a much lower voltage (about 12 volts for example). These starters have a limited life. When the choke has warmed, his head is burned. Also, it is sometimes necessary to change them. Then simply remove them by dislodging the socket on which they are nested. To do this, it is usually done by professionals, electricians, public and private maintenance agents or other authorized holders, in different stages. Firstly, it is necessary to respect basic safety rules, which mainly consist in cutting off the power before the intervention.
