Abstract

PURPOSE: To enable to install two wire paths, by making easy the grasp of the installation position of switch, through the formation of the chime main body with series circuit of the plunger coil and the drive transistor, and of the switch with the push button switch and the display element for illuminated position.
CONSTITUTION: The chime main body 7 is formed by forming the control switch 3 providing the push button switch 1 and the illuminated position display element 2 connected in parallel with the switch 1 and by connecting the series circuit of the chime plunger coil 4 and its driving transistor 5 to the DC power supply 6, and the switch 3 is connected in parallel with the power supply 6 of the chime main body 7 via the resistor 8 for current detection. The turning on or off of the transistor 5 is controlled with the voltage across the resistor 8 placed in the chime main body 7. When the transistor 5 is turned on, the coil 4 is excited and the chime tone is produced.
