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 electrical communication with the upper surface of the upper battery to energize the diode. A slide switch is also include in the bottom of the housing and engages a set of auxiliary contacts on the contact device to provide a selectable on or off position in addition to the momentary contact of the dome.

Claims

1. A flashlight assembly comprising:

a housing having a bottom wall and a side wall extending upwardly from said bottom wall;

a light emitting diode having a head portion and first and second spaced contact arms extending rearwardly from said head portion, said second contact arm having a shorter length than said first contact arm, said diode being received within said housing with said head portion of said diode being received in an aperture in said side wall of said housing, said first contact arm extending along said bottom wall of said housing and being captured within a channel formed in said bottom wall, said second contact arm resting on a raised shoulder formed within said housing;

a battery having first and second contacts, said battery being received within said housing with said second contact in electrical communication with said first contact arm of said diode;

a contact member having first and second ends, said first end being fixed in a stationary positioning electrical communication with said second contact armof said diode, said second end of said contact member being normally biased to a first open position in spaced relation to said first contact of said battery, said second end of said contact clip being selectively depressibly movable between said normally open first position and a second closed position in electrical communication with said first contact of said battery to selectively energize said diode, said contact member further including an auxiliary contact disposed adjacent to said first contact of said battery, said auxiliary contact being normally biased to a closed position in engagement with said first contact of said battery; and

a slide switch being slideably received in said bottom wall of said housing, said slide switch being selectively slideable between a normal first position wherein said slide switch engages said auxiliary contact and forces said auxiliary contact out of engagement with said first contact of said battery and second position wherein said slide switch is disengaged from said auxiliary contact allowing said auxiliary contact to engage said first contact of said battery and energize said diode.

2. The flashlight assembly of

claim 1

wherein said second end of said contact device is a dome switch.

3. The flashlight assembly of

claim 1

wherein said contact device has a top side and a bottom side opposite to said top side, said bottom side being selectively insulated to prevent electrical communication with said battery when said contact device is in said normally open position.

4. A flashlight assembly comprising:

a housing having a bottom wall and a side wall extending upwardly from said bottom wall;

a light emitting diode having a head portion and first and second spaced contact arms extending rearwardly from said head portion, said diode being received within said housing with said head portion of said diode being received in an aperture in said side wall of said housing, said first contact arm extending along said bottom wall of said housing, said second contact arm resting on a raised shoulder of formed within said housing;

a battery having a first contact on an upper surface thereof and second contact on a lower surface thereof, said battery being received within said housing with said second contact in electrical communication with said first contact arm of said diode;

a flexible cover received in assembled relation with said housing to maintain said diode and said battery within said housing;

a contact member having first and second ends, said first end being fixed in a stationary positioning electrical communication with said second contact armof said diode, said second end of said contact member being normally biased to a first open position in spaced relation to said first contact of said battery, said second end of said contact clip being selectively depressibly movable between said normally open first position and a second closed position in electrical communication with said first contact of said battery to selectively energize said diode, said contact member further including an auxiliary contact disposed adjacent to said first contact of said battery, said auxiliary contact being normally biased to a closed position in engagement with said first contact of said battery; and

a slide switch being slideably received in said bottom wall of said housing, said slide switch being selectively slideable between a normal first position wherein said slide switch engages said auxiliary contact and forces said auxiliary contact out of engagement with said first contact of said battery and second position wherein said slide switch is disengaged from said auxiliary contact allowing said auxiliary contact to engage said first contact of said battery and energize said diode.

5. The flashlight of

claim 4

wherein said second contact arm of said diode has a shorter length than said first contact arm.

6. The flashlight of

claim 4

wherein said first contact arm is captured in a channel formed in the bottom wall of said housing.

7. The flashlight of

claim 5

wherein said first contact arm is captured in a channel formed in the bottom wall of said housing.

8. The flashlight assembly of

claim 4

wherein said second end of said contact device is a dome switch.
