.A CORPORATION 0F MASSACHUSETTS SWITCH FOR ELECTRICAL FLASH LIGHTS Application filed January 31, 1928.
This invention relates to improvements in switches for electrical flash lights that are located on the outer surface of the battery enclosing casing. An obj ect of the invention is to provide a switch that permits the circuit to the bulb to be momentarily closedv` or to be locked so that it can not be accidently closed, or to be permanently closed.
Broadly itcomprises a casing member which is attached to the casing and having a slidable thumb and finger piece that is located on its upper surface. This piece Operates a slidable contact closing member that is located within the casing. Also located Within an opening of the casing is a push button for momentarily closing the circuit to the bulb. The slidable member also performs the function of permanently retaining the circuit open to prevent it accidently closing when the fiash light is not in use. Means are also provided for permanently closing the circuit.
Referring to the drawings:

for locking the slidable contact member and the openings to receive the depending portions of the thumb piece.
Referring to the drawings in detail:
1 designates the struck-up casing member which is secured to the battery enclosing tube by means of rivets which enter the openings Q of the flange portion 3. This casing is formed with an opening 4 and the two elongated slots 5. shown in Fig. 9. Located in the opening 1 is a push button 6 that is formed as a part of the member 7 which is formed with the three slots 8, 9 and 10, as shown in Fig. 8. 11 is a slidable contact member that `is located below the slotted plate 7 having the downwardly extending contact closing tongue part 12 which engages the contact 13 of the electric circuit. The slidable contact member 11 is operated b v means of the thumb piece 14 that is formed with the downwardly extending fingers 15 that pass through the slots 5 in the casing and enter the recesses 16 of the slidable contact member 11. They are folded inwardly. as shown in Fig. 6, where they engage the lower surface of the slidable contact member 11. The member 11 is formed with a struck up portion 17 which is designated to enter the slots S, 9 and 10 of the fixed plate 7 for the purpose of holding the slidable Contact member' 11 in different positions of adjustment. The contact member 11 is also formed with recesses 1S. The casing 1 is formed with inwardly extending projections 19 on the opposite edges, as shown in Figs. G, 7 and 9. The purpose of these projections is to prevent the downward movement of the contact member 11 when the thumb 6 is pressed downward. as shown in Figs. 1 and 6. to prevent accidental closing of the circuit. These pieces normally enter the cut out recesses 18 of the member 11.
The operation of the switch may be described as follows: Referring first to Fig. 1. the struck up part 17 of the slidable cont-act member 11 is located in the opening 8 of the fixed plate 7. This part retains the slidablc contact piece 11 against accidental closing of the circuit. In this position the contact is held open. rfhe struck up ears 19 are now under the member ll, Figs. 6 and 'l'.
