Title:
PUSH SWITCH APPARATUS
Document Type and Number:
Japanese Patent JPH1140000
Kind Code:
A
Abstract:

To provide a push switch apparatus which can provide light touch and a reliable operation feeling.

A momentary switch 4 is made to switch before the full stroke by setting the repulsion load of the bent elastic spacer 18 to be the operation load of the switch 4 or higher. After the switching, the pushing force applied to obtain the full stroke of a push operation knob 13 is absorbed by bending again the elastic spacer 18 which is extended by the switching of the switch 4 to prevent the pushing force from directly affecting the switch 4 and in this manner, the switch 4 is prevented from being a stopper at the time of the full stroke. Moreover, the push load on the push operation knob 13 is controlled to be a general specification level (about 10 kgf) for an ordinary switch and at the same time from the starting of push to the full stroke, the switch can be operated with a series of light touch and good operation feeling.
