The Main Parameter Of Micro Switch
Oct 26, 2022
When you choose the micro switch, should pay attention to the following matters:
Main action characteristic parameters of micro switch are defined as follows:
1. Free position (FP) - The actuator is not subjected to operating force (or moment) or the operating force (or moment) is not sufficient to enable it
The position at which the displacement changes.
2. Action position (OP) - the position of the actuator at the instant of forward action of the quick mechanism.
Release Position (RP) - The position of the actuator at the instant of reverse action of the quick mechanism.
3. Full TRAVEL POSITION (TTP) - THE position at which the actuator is stopped.
Action stroke (pre-stroke PT) - displacement of actuator from free position to action position.
4. Over travel (OT) - Actuator automatically moves from position to full stroke position.
5. Differential STROKE (DT) - Displacement of actuator from automatic position to release position.
6. Full travel (TP) - Displacement of actuator from free position to full stroke position.
7. Action force (OF) - the operating force required to move the actuator from the free position to the action position.
8. Release force (RF) - The actuator returns to the release position from the forward position and the operating force (or moment) must be reduced to
The numerical values.
9. Full force force(TF) - the minimum operating force (or moment) of the actuator at the full stroke position.
