Title:
遅延スイッチ
Document Type and Number:
Japanese Patent JP4199860
Kind Code:
B2
Abstract:
Disclosed is an improved operation-staggered dual switch (1) having first and second switching mechanisms (A and B) installed in its casing (2). These switching mechanisms are so operatively connected that the operation of the first switching mechanism (A) may follow the operation of the second switching mechanism (B) after a predetermined delay. The first switching mechanism (A) is equipped with delay means, which comprises a connection rod (17,17e,17g) having indentations formed on one side, a train of toothed wheels (18,19,20a) and a rotary damper (20). The leading toothed wheel (18) of the train of toothed wheels is engaged with selected indentations of the connection rod, and the rotary damper (20) is integrally connected to the trailing toothed wheel of the train of toothed wheels. The connection rod is responsive to the start of operation of the first switching mechanism (A) for loading the first switching mechanism with the train of toothed wheels (18,19,20a) and the rotary damper (20), all of which start clockwise or counter-clockwise rotations to retard the turning-on of the first switching mechanism.
