Document Type and Number:
WIPO Patent Application WO/2019/225635
Kind Code:
A1
Abstract:
The present disclosure addresses the problem of making it less likely that a clicking feel presented to an operator upon pressing a pushing element is reduced. A push switch (1) is provided with: a case (2) having a fixed contact portion (7); a movable member (3); a pushing element (5); and a support portion (6). The movable member (3) includes a movable contact portion (8). The movable member (3) is disposed in a position opposing the fixed contact portion (7), and is moveable between an on-position and an off-position. The pushing element (5) is disposed in a position opposing the movable member (3), and presses the movable member (3) due to an external force. The support portion (6) has characteristics such that the load acting on the pushing element (5) from the support portion (6) increases until the amount of movement of the pushing element (5) reaches a first threshold value, and such that the load acting on the pushing element (5) from the support portion (6) decreases when the amount of movement of the pushing element (5) has reached the first threshold value.
