Title:
CONTROL APPARATUS FOR SWITCH AND ELECTRONIC WHISTLE
Document Type and Number:
WIPO Patent Application WO/2017/045167
Kind Code:
A1
Abstract:
A control apparatus for a switch. The control apparatus is fixed on a housing (100). The control apparatus comprises a button (300) matching a switch (410) in the housing (100). The control apparatus also comprises a partition (350) provided between the button (300) and the switch (410). The housing (100) is provided with a switch opening (121) corresponding to the switch (410). The partition (350) fits a sidewall surrounding the switch opening (121) and seals the switch opening (121). The button (300) is provided with a trigger point (310) arranged at the position of the switch opening (121). The trigger point (310) is smaller than the switch opening (121). A pressing force is applied on the button (300); the trigger point (310) is abutted against the partition (350) to distend the partition (350) to trigger the switch (410). When the force transmitted by the button (300) is applied on the partition (350), a part of the force acts on the sidewall surrounding the switch opening (121), while a part of the force is used in triggering the switch (410). As such, if the pressing force is too weak, then the partition cannot be distended and thus the switch cannot be triggered, thus preventing the switch from being triggered due to the button being touched inadvertently and preventing misuse.
