Abstract
A miniature flashlight consists of a housing, a light emitting diode (LED), a pair of batteries, and a flexible cover and a contact device that acts as both a momentary contact and a conventional switch. The LED is received in a seat formed in the housing with the head portion of the diode received in an aperture in the side wall of the housing. A longer contact arm is captured in a channel formed in the bottom wall. A shorter contact arm rests on a shoulder that forms part of the LED seat. A pair of coin cell batteries are received within another seat formed in housing. The lower battery sits on top of the longer contact arm captured in the channel of the bottom wall. A resilient plastic cover is assembled with the housing to maintain the diode and the batteries within the housing. The first end of the contact clip is frictionally engaged by pins within the housing and a contact arm engages the second contact of the diode, while the opposing second end is a dome switch disposed in spaced relation over the upper surface contact of the upper battery. The cover is selectively depressible, i.e. deformable, to selectively depress the dome on the second end of the contact device into el…
