A control module (18) advantageously reduces cost and enhances reliability, design flexibility, ease of assembly, and performance of a flywheel operated hand tool (10). The control module (18) includes a thin film printed circuit with non-contact speed sensing of a flywheel to more accurately set the target speed and control transfer kinetic energy thereof to a fastener, achieving a desired depth regardless of variations in component performance and battery voltage. The printed circuit also includes long service life thin film switches for responding to trigger (30) and safety (34) inputs. Furthermore, the control module (18) responds to a user speed selection (40) and to preset speed selection ranges to reconfigure the controls as appropriate to constraints of a fastener drive assembly and to user preferences.
Cette invention concerne un module de commande (18) pour un outil manuel entra¹n~ par volant (10) qui offre divers avantages en termes de fiabilit~, de souplesse de conception, de facilit~ de montage et de performances Le module de commande (18) comprend un circuit imprim~ ~ film mince avec d~tection sans contact de la vitesse du volant, ce qui permet de r~gler avec une plus grande pr~cision la vitesse recherch~e, de transf~rer de l'~nergie cin~tique ~ une fixation et d'atteindre la profondeur requise ind~pendamment de variations concernant les caract~ristiques des composants et la tension des piles. Le circuit imprim~ comporte ~galement des commutateurs durables ~ film mince qui interviennent en r~ponse aux sollicitations de la d~tente (30) et ~ des consignes de s~curit~ (34). De plus, le module de commande (18) r~agit ~ la s~lection de vitesse (40) faite par l'utilisateur et ~ des plages de s~lection de vitesse pr~r~gl~es, ce qui permet de reconfigurer les commandes au gr~ des contraintes impos~es ~ l'ensemble entra¹nement de fixations et des pr~f~rences de l'utilisateur.
