Abstract
A push switch includes: a case including a fixed contact; a movable member, a pushing element, and a support. The movable member includes a movable contact. The movable member is disposed at a location to face the fixed contact and is movable between an ON-position and an OFF-position. The pushing element is disposed at a location to face the movable member and is configured to receive external force to push the movable member. The support has such a property that until a travel distance of the pushing element reaches a first threshold, a load applied from the support to the pushing element increases, and when the travel distance of the pushing element reaches the first threshold, the load applied from the support 6 to the pushing element decreases.
Claims17
A push switch, comprising:
- a case including a fixed contact;
- a movable member including a movable contact, disposed at a location to face the fixed contact, and movable between an ON-position at which the movable contact is in contact with the fixed contact and an OFF-position at which the movable contact is apart from the fixed contact;
- a pushing element disposed at a location to face the movable member and configured to receive external force to push the movable member;
- and
- a support connected to the pushing element and supporting the pushing element with respect to the case,
- the support having such a property that until a travel distance of the pushing element reaches a first threshold, a load applied from the support to the pushing element increases, and after the travel distance of the pushing element reaches the first threshold, the load applied from the support to the pushing element decreases,
- the movable member having such a property that until the travel distance of the pushing element reaches a second threshold, a load applied from the movable member to the pushing element increases, and when the travel distance of the pushing element reaches the second threshold, the load applied from the movable member to the pushing element decreases.
