Embodiment Construction

[0005] The present invention will be further described below in conjunction with embodiments and drawings.

[0006] Main dual-contact mechanical timer. 1 It not only controls the power on and off of the power sockets Czl and CZZ, but also controls the power on and off of the secondary double-contact mechanical timer DZ. The secondary double-contact mechanical timer DZ only controls the power on and off of the power sockets Czl and CzZ. The timing time of the secondary double-contact mechanical timers D1 and D2 are respectively set to TD1 and TD2. When using, first set the time TD1 and TD2. After connecting the power supply, the power sockets CZ1 and CZ2 are in power on and off respectively. Status. After the time TD1 has elapsed, the power sockets Cz1 and CZ2 change to be in the power off and on state respectively. After the time TD2 has elapsed, the power sockets Cz1 and Cz2 are restored to their initial on and off states respectively, thus realizing the function of timing powe...

Abstract

The present invention discloses a mechanical timing combination switch which is obtained through combining a main double-contact mechanical timer, an auxiliary double-contact mechanical timer and two power sockets. The main double-contact mechanical timer and the auxiliary double-contact mechanical timer are convection type double-contact mechanical timers which are modified by the prior moving switching-off type single-contact mechanical timers and are firstly switched off and afterwards switched on. The mechanical timing combination switch of the invention has the following advantages: low cost, simple use method and wide application range. Particularly stable and reliable timing is obtained. Furthermore the mechanical timing combination switch is not affected by power failure.

Description

Technical field [0001] The invention relates to electronic equipment, in particular to a mechanical timing combination switch. Background technique [0002] At present, the existing mechanical timer has only one set of contacts, and its application range is limited. To a large extent cannot meet the needs of users. Summary of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and propose a mechanical timing combination switch. The purpose of the present invention is achieved through the following technical solutions. The invention is composed of a main and auxiliary double-contact mechanical timer and two power sockets. The primary and secondary double-contact mechanical timers are the conversion of the existing dynamic-break single-contact mechanical timers into a switch-off double-contact mechanical timer that breaks and then closes, that is, the single-sided moving contact on the original spring sheet Changed to a do...
