Abstract
An electrical switch has a fixed contact and a moving contact moving between a first position in contact with the fixed contact and a second position not in contact with the fixed contact. An operating mechanism moves the moving contact and includes a resiliently biased presser resiliently pressing upon the moving contact while riding in opposite first and second directions past a barrier associated with the moving contact, and a spring having first and second parts acting on first and second sides of the presser to maintain the presser in a neutral position and providing extra biasing force to assist the presser in moving faster upon riding past the barrier.
