Claims

[Claims for Utility Model Registration] 1. A pressing speed detection device that is composed of at least two switches and detects pressing speed based on the time difference between the switching operations of these switches, which comprises (a) a substrate and (b) ) The first and second members are arranged in layers so as to be sandwiched in a sandwich-like manner with the substrate interposed therebetween, and each of the first and second members is a support fixed to the substrate. and a movable part that is elastically movable relative to the support part by force from the first member toward the second member, and the first member The movable portion of the first member is bulged out so as to form a space between the movable portion of the first member and the second member, and the movable portion of the first member and the second member The first and second members are connected by a connecting portion that connects the first and second members so that a pressing force from one member to the second member is transmitted to the movable portion of the second member. The two switches each have a pressed portion between the movable portion of the first member and the substrate and between the movable portion of the second member and the substrate. A pressing speed detection device characterized by being interposed. 2. An airtight space is formed by being surrounded by the first and second members and the substrate in an airtight or substantially airtight manner, and this airtight space has a first contact with the substrate during the relative movement of the movable part. 2. The touch response device according to claim 1, wherein air movement gaps are formed so that air can move alternately toward the first member side or the second member side.
