Sliding-controlled three-mode switch timer

Abstract

The invention discloses a sliding-controlled three-mode switch timer. The timer comprises a timing device, a driving motor, a gear drive system, a microswitch, a cradle and a toggle switch, wherein the timing device is used for setting a timing time; the driving motor is used for providing power for the timing device; the gear drive system is used for conducting the power of the driving motor to the timing device; the microswitch is controlled by the timing device and then connects and disconnects the current; the cradle is used for conducting the action of the timing device to the microswitch and controlling the opening and closing of contacts of the microswitch through a press rod; the toggle switch for controlling the press bar to act is arranged between the cradle and the microswitch and connected with the press rod through a slider which moves simultaneously with the toggle switch and can slide on the press rod; and three working modes of timing, normal on and normal off of the timer are achieved through three toggling positions of the toggle switch. According to the timer, the three modes of timing, normal on and normal off can be achieved automatically, and the application range and the flexibility of the timer are improved.

Description

technical field [0001] The invention relates to a timing device, in particular to a timer capable of controlling the on-off time of a load current, and the timer has three states of timing, long-on and long-off under manual control. Background technique [0002] The timers in the prior art generally include a motor, a micro switch, and a timing device for setting the time. The working principle is that the motor drives the gear to drive the timing device to work. The switch operates to disconnect the controlled circuit. The timing range of this type of timer is generally 24 hours or a cycle, that is, the scale circle on the timing device works in a circle after 24 hours or a week, that is, all timing points will be triggered within this week, and the opening of the micro switch here Closing is only controlled by the insert on the timing device, that is, when the timing point is reached, the protruding timing insert on the timing device will directly or press the switch of t...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problem that the toggle switch of the timer in the prior art can only be set to two working states of long on and timing, and the linkage between the micro switch and the insert of the timing point is not controlled, resulting in a relatively single function of the timer. The invention provides a toggle switch that controls the connection state between the micro switch of the timer and the insert piece of the timing point, so as to realize the adjustment of the working state of the timer itself, so as to achieve the effect of flexibly controlling the time period set by the timer
