Technical terms related to the position of a push button (actuator)
(1) Free Position (FP)
State in which a pressing object does not touch the push button
(2) Operating Position (OP)
Position where the movable contact flips
![2.Operating Position (OP) - 動作位置‐可動接点が反転する位置](http://ac-blog.panasonic.com/hs-fs/hubfs/blogimg/beginner/switch/micro/kiso_02_01_Img_03_en.jpg?width=600&name=kiso_02_01_Img_03_en.jpg)
(3) Total Travel Position (TTP) - Travel Limit Position -
Position where the push button is pressed to the limit
![3.Total Travel Position (TTP) - 動作限度位置 -押しボタンを押し切った状態 3.Total Travel Position (TTP) - 動作限度位置 -押しボタンを押し切った状態](http://ac-blog.panasonic.com/hs-fs/hubfs/blogimg/beginner/switch/micro/kiso_02_01_Img_04_en.jpg?width=600&name=kiso_02_01_Img_04_en.jpg)
(4) Releasing Position (RP)
Position where the movable contact returns from the Operating Position to the original position
![4.Releasing Position (RP) - 戻りの位置‐可動接点が動作位置から元の位置へ戻る位置 4.Releasing Position (RP) - 戻りの位置‐可動接点が動作位置から元の位置へ戻る位置](http://ac-blog.panasonic.com/hs-fs/hubfs/blogimg/beginner/switch/micro/kiso_02_01_Img_05_en.jpg?width=600&name=kiso_02_01_Img_05_en.jpg)

Technical terms related to the movement of the push button (actuator)
(1) Pre-Travel (PT) - Movement from the Free Position to the Operating Position -
Distance covered by the push button from the Free Position to the Operating Position
![1.Pre-Travel (PT) - 動作までの動き - Free Position から Operating Position までの移動距離](http://ac-blog.panasonic.com/hs-fs/hubfs/blogimg/beginner/switch/micro/kiso_02_01_Img_07_en.jpg?width=600&name=kiso_02_01_Img_07_en.jpg)
(2) Over-Travel (OT) - Movement from the Operating Position to the Total Travel Position -
Distance covered by the push button from the Operating Position to the Total Travel Position
![2.Over-Travel (OT) - 動作後の動き - Operating Position から Total Travel Position までの移動距離](http://ac-blog.panasonic.com/hs-fs/hubfs/blogimg/beginner/switch/micro/kiso_02_01_Img_08_en.jpg?width=600&name=kiso_02_01_Img_08_en.jpg)
(3) Total-Travel (TT) - Entire Movement -
Total of 1. Pre-Travel, and 2. Over-Travel
![3.Total Travel (TT) - 全体の動き - 1.Pre-Travel と 2.Over-Travel の合計](http://ac-blog.panasonic.com/hs-fs/hubfs/blogimg/beginner/switch/micro/kiso_02_01_Img_09_en.jpg?width=600&name=kiso_02_01_Img_09_en.jpg)
(4) Movement Differential (MD) - Differential between the Operating Position and the Release Position -
Movement Differential = Differential between the Operating Position and the Release Position
![4.Movement Differential (MD) - 応差の動き‐Operating Position と Releasing Position の差=動作の位置と戻り位置の差](http://ac-blog.panasonic.com/hs-fs/hubfs/blogimg/beginner/switch/micro/kiso_02_01_Img_10_en.jpg?width=600&name=kiso_02_01_Img_10_en.jpg)

Technical terms related to the forces applied to a push button (actuator)
(1) Operating Force (OF) - Force required to operate an actuator -
Force applied to move an actuator (push button) from the Free Position to the Operating Position
(2) Total Travel Force (TF)- Force Required for the Entire Push Button Movement -Required force applied to move an actuator from the Operating Position to the Total Travel Position
![2.Total travel Force (TF) - 全体の動きに必要な力‐Operating Position から Total Travel Position まで動かすのに必要なアクチュエーターに加える力](http://ac-blog.panasonic.com/hs-fs/hubfs/blogimg/beginner/switch/micro/kiso_02_01_Img_13_en.jpg?width=600&name=kiso_02_01_Img_13_en.jpg)
(3) Release Force (RF)- Force Required to Move a Push Button from TTP to RP
Required force applied to move an actuator from the Total Travel Position to the Release Position
![3.Releasing Force (RF) - もどりの力‐Total Travel Position から Release Position まで動かすのに必要なアクチュエーターに加える力](http://ac-blog.panasonic.com/hs-fs/hubfs/blogimg/beginner/switch/micro/kiso_02_01_Img_14_en.jpg?width=600&name=kiso_02_01_Img_14_en.jpg)
