In the embodiment of the connection switch, since the shorted

metal terminals

41a and 41b are connected by rainwater, the electrical resistance of the rainwater is increased, thereby weakening the voltage applied to the light emitting device 30. In order to prevent the power applied to the device 30 from being weakened, it is preferable that a transistor Q1 is provided between the

metal terminals

41a and 41b and the light emitting device 30 as shown in FIG. 8. Do. At this time, when the rainwater does not flow and the

metal terminals

41a and 41b remain shorted, the transistor Q1 does not supply current to the light emitting device 30 in the off state, but rainwater flows into the metal terminals. When 41a and 41b are connected by rainwater, as the power is amplified while the transistor Q1 is turned on, a voltage of a predetermined magnitude or more is supplied to the light emitting element 30 so as to emit light.

Therefore, the operation of the umbrella light emitting device configured as described above is as follows.

At this time, when the push button 42 is pressed, the light emitting element 30 and the

metal terminals

41a and 41b are kept connected to each other as the push switch 43 is pressed. Of course, if there is no rain, since the

metal terminals

41a and 41b are kept short-circuited, the power of the battery 20 is not supplied to the light emitting element 30 and thus does not emit light. However, when it rains, as the rainwater flows into the grooves of the cap 14 or the waterproof member 15, as shown in FIGS. 6 to 8, the rainwater is short-circuited with each other, the

metal terminals

41a and 41b. The transistor Q1 is turned on as the connection is made. Of course, if rain is stopped or rainwater is removed from the groove of the cap or waterproof member 15 due to the downward movement of the umbrella head, the shorted state as rainwater is removed between the pair of

metal terminals

41a and 41b. In this case, the light emitting device 30 is not operated because the power of the battery 20 is blocked from being supplied to the light emitting device 30. On the other hand, as described above, when the push button 43 is pressed by pressing the push button 42, the pair of

metal terminals

metal terminals

41a and 41b and the light emitting element 30 even when the pair of

metal terminals

41a and 41b are connected to each other. Is short-circuited and thus the power of the battery 20 is not supplied to the light emitting element 30, so that light emission does not operate.
