A release switch device includes: a button; a first elastic member to be pressed and displaced by the button; a pressure-sensitive sensor to face the first elastic member at an interval, to be pressed and displaced by the button with interposition of the first elastic member, when the button is displaced exceeding a predetermined stroke amount; and a second elastic member to be pressed and displaced by the button with interposition of the first elastic member and the pressure-sensitive sensor. When the button is displaced by a first stroke amount equal to or larger than the predetermined stroke amount, the pressure-sensitive sensor receives a first repulsive force of the second elastic member and outputs a first output value. When the button is displaced by a second stroke amount larger than the first stroke amount, the pressure-sensitive sensor receives a second repulsive force larger than the first repulsive force of the second elastic member and outputs a second output value.

The present disclosure belongs to the technical field of switches, and particularly relates to a button switch. The button switch comprises a base, an upper cover plate and a lower cover plate are arranged on the upper side and the lower side of the base respectively, a circuit board is arranged in the base, input wiring terminals and output insertion pieces are connected to the circuit board, a switch assembly for controlling the communication of the input wiring terminals and the output insertion pieces is arranged between the input wiring terminals and the output insertion pieces The button switch is stable in use process, stable in contact, long in service life, not prone to damage and convenient to maintain, and can be widely applied to various handheld electric tools.

A base element and at least one switching element are included in an operator control device which may be disposed in a vehicle. By closing at least one electrical contact, the switching element is moveable from a first position into a second position relative to the base element. The operator control device can also include at least one pushbutton switch moveable relative to the base element between a position of rest and at least one activation position. The operator control device can further include at least one restoring element, formed of silicone and supported on the base element and on the pushbutton switch, which can be elastically deformed by moving the pushbutton switch from the position of rest into the activation position. Using the restoring element, the pushbutton switch can be moved from the activation position into the position of rest by relaxing the restoring element.
