A pushbutton switch has a base and a button telescopically movable on the base. There are a pair of terminals, with one of the terminals having a contact arm positioned within a switching chamber in the base. Movement of the button is effective to cause the contact arm to close upon the other terminal. The effective length of the contact arm is greater than its actual length. In one improvement, a light emitting device may be illuminated when the switch is operated. In another, a portion of the light emitting device forms the means to close the contact arm.
