Caution on Mechanical Characteristics |
| |
| 1. Operating Force and Stroke |
| |
Stroke setting is very important for high reliability. Setting in a proper contact force range is also important to ensure high reliability.
For normal-close circuit (NC), a driving mechanhism should be set so that an actuator should be in the free position.
For normal-open circuit, (NO), an actuator should be pressed to the maximum of the specified stroke to absorb possible errors and shake.
If the stroke setting is too close to operating point (OP), or release position (RP), contact force may become unstable and vulnerable to vibration and shock. It also becomes hard to keep contact reliability.
The following is correlation diagram of operating force, stroke and contact force. |

| 2. Changes in Operating Characteristics |
| |
Extra care is needed on designing so that malfunctions will not occur when switch's characteristics vary in some measure. |
| |
| 3. Operating Frequency/ Speed |
| |
Operating frequency/speed greatly affect switch's performance. Please verify both operating frequency/speed.
3 - 1
Exceedingly fast operating speed can not only cause damage but contact switching may not be able to catch up.
3 - 2
Exceedingly slow operating speed can make contact switching unstable. It may cause contact failure or welding problems.
3 - 3
An exceedingly low frequency can generate a film on the surface of the contact which may cause contact failure. |

| 4. Operation |
| |
Do not apply any shock to the actuator. The following is inappropriate operation method. |
