1480957 Electric battery lamps MABUCHI MOTOR KK 23 Aug 1974 [25 Aug 1973 (2) 27 Aug 1973 4 March 1974] 37272/74 Heading F4R [Also in Divisions H1 and H2] A device for charging one or more nickel cadmium cells 3 from primary cells 8 (see Division H2) may be adapted for use as a hand lamp. As shown in Fig. 19, primary cells 8 are held in a lower casing section of deformable plastics, to which is attached a further section 1 having a push button 5 to control charge and discharge of a nickel cadmium cell 3. A further casing section 27 containing a lamp 30 and reflector 28 may be attached when the device is for use as a hand lamp. In Fig. 20, the lamp 30 is inserted into a tube through the casing 2 housing the primary cells 8 and is provided with a reflector 28 and cover glass 29. Mechanical switches.- Fig. 21 shows a changeover switch operable by a push button 14 located in a recess in the upper casing 1. The U-shaped change-over contact 15 normally engages a fixed contact 49 but on depression of the push-button 14, a screw 46 depresses the upper limb of the change-over contact 15 into engagement with a normally-open fixed contact 12 mounted on a resilient arm. Further depression of push button 14 causes a sliding movement between contacts 15 and 12 so that the switch is self-cleaning. |
