2. Ordinary switches have only two accessions. In this case on one of contacts always there has to be tension (+), and after switching off as well on the second. There are switches with several contacts. It is necessary to find out from such switches according to the scheme where tension moves. If necessary it is possible to include ignition.
3. By means of a control lamp check whether there is tension on the output plug. If tension is, the switch is serviceable.
4. If on the entrance plug there is no tension, there is a break in a food cable. By means of the electrical circuitry it is necessary to check a wire of tension and if necessary to replace a wire. |
