Thus, beads or candida counters are on the market, for example application numbers: 201922487028.3, publication No. CN211124123U, which discloses a bead-dialing counter, which uses a ball-dialing switch to trigger a dome switch to count.
However, the existing beads or nostoc counters adopt contact-type micro switches or elastic switches to trigger counting, and have the following defects:
firstly, with the increase of the number of times of use, the elasticity of the elastic sheet of the contact-type microswitch or elastic sheet switch is reduced, even the elasticity is lost, so that the final counting is inaccurate, even the counting cannot be performed.
Secondly, for the believer, many people are in ordinary life, and the habit is hand-carried the beads, habitually stirs the beads at any time when idle, and this makes the frequency of use of beads very high, and for the counter that adopts contact touch switch to count, the increase of frequency of use makes the life-span of counter shell fragment switch or micro-gap switch shorten with higher speed. In addition, in the prior art, when a microswitch or a dome switch is assembled, a worker holds the microswitch or the dome switch to easily touch an elastic sheet on the switch due to the small volume of the microswitch or the dome switch, the elastic sheet on the switch is easily pinched, bent and deformed, and when the deformation is large, the microswitch or the dome switch cannot be touched, so that the counting is disabled.
Third, it is thought that a quiet environment is generally required, and the conventional touch switch generates noise and has a feeling of frustration.
Finally, existing counters use contact switches that wear out the beads over time.
