Switch apparatus

A switch apparatus adapted to be assembled with a casing of an electronic product, comprising:

• a control device comprising a base portion having two opposite end portions, an opening, an accommodating space communicating with the opening and defined in the base portion, a position portion, at least a pressing portion formed on a side of the base portion adjacent to the opening, and at least a linking portion having one end connected to the casing of the electronic product;
• a resilient element being installed in the control device, and having a fixing portion, at least a deforming portion and a contact portion extending from a free end of the at least a deforming portion, the fixing portion being fixed into the position portion and bent to form the at least a deforming portion, the at least a contact portion located with respect to the pressing portion of the control device;
• and
• at least a triggering device being electrically connected with the electronic product, and having a bearing surface facing the contact portion of the resilient element;
• wherein when the control device is being pressed with a first force, the at least a pressing portion presses against the contact portion of the resilient element, whereby the bearing surface of the at least a triggering device is being pushed downwards by the contact portion so as to trigger the at least a triggering device, while the control device is being pressed with a second force larger than the first force, the at least a deforming portion deforms, and the contact portion continues pressing against the bearing surface.
