Adjustment switch, английский
- A device which allows longitudinal rail movement to dissipate thermal forces when cwr is adjacent to jointed track or other features not designed to withstand thermal forces. adjustment switches are also used when thermal forces, additional to those in cwr, may be encountered such as at long under-bridges which are themselves subject to expansion and contraction (us term: breather switch). rt
