Title:
TRIGGER SWITCH
Document Type and Number:
Japanese Patent JP2022118534
Kind Code:
A
Abstract:
To provide a trigger switch that determines a push-in amount of a trigger subjected to a push-in operation in a non-contact manner and can eliminate effects of magnetic fields in the external environment.SOLUTION: A trigger switch TS comprises: a first conductive plate 40 (movable electrode) that moves as a trigger 1 is moved by a push-in operation; and a second stationary electrode 51 (stationary electrode) that is placed near and at an interval from a moving range of the first conductive plate 40 and forms a capacitor together with the first conductive plate 40. An electrostatic capacity of the capacitor formed from the first conductive plate 40 and the second stationary electrode 51 of the trigger switch TS varies along with the movement of the first conductive plate 40.SELECTED DRAWING: Figure 3
