SENSOR-CONTAINING HAZARD DETECTOR BUTTON WITH OPTIMIZED TACTILE CHARACTERISTICS

摘要

According to one embodiment, a displacement control member may be operationally coupled with a selectable button of a hazard detector so that axial depression of the selectable button effects pivoting of the selectable button and the displacement control member into contact with a switch of the hazard detector. The displacement control member may be coupled with the selectable button so that a ratio of a distance from the switch to a point of user contact with the selectable button and a distance from the switch to a pivot point of the displacement control member is similar regardless of where the user contacts the selectable button. The displacement control member may equalize a user input force that is required to activate the hazard detector's switch.

1. A hazard detector for detecting the presence of a hazard in a building or structure, the hazard detector comprising:
a housing having an interior region within which components of the hazard detector are contained, the housing having a plurality of openings through which air flows so as to be accessible to a hazard sensor positioned within the interior region of the housing; a selectable button positioned on a front portion of the hazard detector so as to face and be selectable by a user when the hazard detector is mounted on a wall or ceiling of the building or structure; a switch disposed within the housing and axially under the selectable button, the switch being positioned radially offset from a central axis of the selectable button and being activatable upon user selection of the selectable button; and a displacement control member disposed within the housing between the selectable button and the switch, the displacement control member being operationally coupled with the selectable button so that axial depression of the selectable button effects pivoting of the selectable button and pivoting of the displacement control member into contact with the switch, the displacement control member being configured to equalize a user input force that is required to activate the switch by being coupled with the housing and selectable button so that a ratio of a radial distance from the switch to the user input force and a radial distance from the switch to a pivot point of the displacement control member is similar regardless of where the user selects the selectable button.
