Item

Explanation

Figure

Operation Force

It refers to the maximum load at the time of switching over of the contacts.(Point A in the figure)

 

Return Force

It refers to the returning force of the stem after its full travel when pushed out.(Point B in the Figure)

Click
(tactile Feedback)

It refers to the feeling indicated on the inversion portion in the operating force us. Travel diagram shown en the figure.
The greater this inversion part is, the clearer it is to the operator that the switch is moved.

Travel

It refers to the distance of travel of the operating part before the contacts is changed over. Generally, it is about 0.3mm in mechanical contact.

Bounce

This refers to the state of repeating the contact opening or closing momentarily at the time of the changeover of the swich to ON or OFF longer duration of this state may cause malfunction of the signal
