A switch (1200) as for a flashlight (10) selectively connects, for example, a solid state light source (100) and a battery (60) in the flashlight (10) in circuit for causing the light source (100) to produce light. The switch (1200) comprises a pushbutton (1210) and a metal contact (1220) having a periphery that selectively contacts a housing (20), and a spring (1226). Pressing the pushbutton (1210) moves the pushbutton (1210) and the metal contact (1220) to contact the housing (20). The metal contact (1220) may include a feature for centering the metal contact (1220) with respect to the pushbutton (1210) and thus with respect to the housing (20). The switch (1200) may be disposed in a tail cap (40) attached to a flashlight housing (20).

La présente invention concerne un commutateur (1200) de lampe-torche (10) y établissant sélectivement un circuit comportant une source lumineuse à semi-conducteurs (100) et une pile ou batterie (60) de façon à faire produire de la lumière par la source lumineuse (100). Le commutateur (1200) comporte un bouton-poussoir (1210), un contact métallique (1220) dont le pourtour touche sélectivement le carter (20), et un ressort (1226). En appuyant sur le bouton-poussoir (1210), on déplace le bouton-poussoir (1210) et le contact métallique (1220) jusqu'à toucher le carter (20). Le contact métallique (1220) peut comporter un dispositif pour centrer le contact métallique (1220) par rapport au bouton-poussoir (1210), et donc au carter (20). Le commutateur (1200) peut être disposé dans un capuchon d'assemblage (40) solidaire du carter (20) de la lampe-torche.
