Abstract
Battery holder 10 includes a housing 12 with a recess 14 for receiving a battery 16. The housing 12 supports a first electrical contact 18, a second electrical contact 20 and a third electrical contact 22. First contact 18 makes electrical contact with a first terminal 24 of the battery 16. The second electrical contact 20 is at an opposite end of the housing 12 and makes electrical contact with second terminal 26 of battery 16. The third electrical contact 22 does not make direct contact with the battery 16. Rather, contact 22 is in electrical contact with one end of a switch 28 supported by the housing 12. Switch 12 is in the form of an elongated strip 30 of electrically conductive material seated in and along a groove 31 formed on an outer surface of the body 12, and is provided with an upstanding finger or tang 32. Switch 28 is selectively switchable between an OFF state in which finger 32 is spaced from contact 18, and an ON state where the finger 32 contacts the contact 18, effectively placing contact 22 in electrical contact with terminal 24 of battery 16.
