A prismatic bar 18 having a square cross-section is provided in a rotation shaft 16 to which plug terminals 14 are fixed and, the rotation shaft 16 is sandwiched between a pair of elastic pieces 17a, 17a of an elastic holder 17, so that the respective elastic pieces 17a, 17a are brought into contact with plane surfaces of the prismatic bar 18 parallel to each other. Therefore an interval, between the two elastic pieces 17a 17a of the elastic holder 17, is increased when the square bar 18 rotates and thus, a firm and, steady touch of a click can be provided.

Why it's free to use
- Filed April 26, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 26, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 26, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
