Switch

An improved switch for generating an electric signal output to control desired function switching or selection operations, comprising:

• a seat having a thick section which includes a first housing section and a second housing section, and an operating space corresponding to the first housing section, the first housing section having a spindle located therein;
• a button key located in the first housing section having an arched key cap which connects a neck, the neck connecting a rotary section which has a pivotal section extending thereabove to pivotally engage with the spindle, the pivotal section having a peripheral rim to form an operating section;
• a first elastic element located on one side of the rotary section having a pair of symmetrical anchor sections which are mounted to jutting sections located on a back side of the rotary section, and having two sides extending to form a pair of symmetrical contact ends;
• a second elastic element located on the operating section having a winding section which is located on an outer rim of the pivotal section, the winding section having two free ends pivotally connecting the second housing section;
• and
• a cap being sealed to the surface of the thick section of the seat;
• wherein the button key is movable forwards or rearwards, or depressable downwards by an external force for turning the rotary section such that the free ends of the second elastic element are moved slowly into the second housing section and contact side walls of the second housing section to allow users having a touching sense of button key movement to increase operation touch feeling.
