Document Type and Number:
WIPO Patent Application WO/2017/201819
Kind Code:
A1
Abstract:
A light controlled timer, comprising a timer socket (2) and a timer plug (1). The timer socket (2) is connected with an input/output device. The timer plug (1) comprises a setting disc (13), an upper housing (11) provided with a window, and a lower housing (12) detachable from the upper housing (11). A circuit board A (111) connected with a coding switch (112) by means of a metal sheet, and a circuit board B (121) provided with a relay (122) and connected with the circuit board A (111), are provided between the upper housing (11) and the lower housing (12). A photoelectric sensing device is provided on the circuit board A (111). The setting disc (13) is connected with the coding switch (112). The circuit board B (121) is connected with a conducting strip (123) fixedly mounted on the lower housing (12). The timer plug (1) is matched and connected with the timer socket (2) by means of the conducting strip (123). The invention modularizes the timer, and therefore facilitates replacement and maintenance of the timer apparatus, and can reduce waste and save resources. Moreover, the timing adjustment using a knob makes it easy and intuitive to operate the timer; the use of the timer is simple, fast and convenient.
