  • Can retain up to 100 N.
  • Push button press count resistance is 10,000 times (reference value).

Precautions for Use

  • Use CUSB while fixed to a device/machine or bottom cover CUSB-BC. The square shaft will not be retained if using without installing to a device/machine or bottom cover.
  • Insert the square shaft after securing CUSB to a device/machine or bottom cover. If the square shaft is inserted first, CUSB may be damaged.
  • If only one side of the push button is pressed after locking, the lock in the direction the push button is pressed will release.
  • CUSB is a product that uses friction fastening. In cases where oil, etc. adhered to the square shaft causes the friction coefficient to decrease or if impact loads or vibrations occur, the maximum retention force may decrease.
  • The surface may be scratched depending on the material and surface finish of the square shaft.
  • If excessive loads are applied, then the square shaft may be scratched or CUSB may be damaged.
  • If excessive loads are applied and the push button is locked, operate the push button after loosening the bolts securing CUSB. CUSB may be damaged if operation is forced.

Usage Example
