Technical Information Standard glossary Fixed rating values The values that guarantee the standards for the limit switch characteristics and functions. For example, the rated current and rated voltage, which are preset conditions (load type, current, voltage, frequency, etc.) Operating object The mechanism and mountings that operate the limit switch actuator. Used for mechanical operators such as cams and dogs. Detective object The unit other than mechanical mountings that operate the limit switch. Products, parts, jigs, etc. Reaction spring (movable spring) The mechanical part that...

Operating characteristics Operating Force (O.F.) The force required to cause contact snap-action. It is expressed in terms of force applied to the actuator. Release Force (R.F.) The force to be applied to the actuator, at the moment contact snaps back from the operated position to unoperated position. Total Force (T.F.) The force required to make the actuator travel to overtravel position. Pretravel (P.T.) Distance of the actuator movement from free position to operating position. Overtravel (O.T.) The distance which the actuator is permitted to travel after actuation without any damage to...
