Abstract

PURPOSE:To decrease the number of switches and to attain the miniaturization of a control switch, by using properly a switch in two functions in accordance with the time of operation of the switch. CONSTITUTION:The signal of an operation switch SW is applied to a time limiting timer TA serving as the 1st output means as well as to a time limit resetting timer TB which is a component element of the 2nd output means. The timer TA works continuously until it is turned off in a certain time in case the switch SW is turned on for a comparatively long certain time. Thus the 1st load controlling signal is applied to an output terminal P1 over the working time of the timer TA. The timer TB works immediately with the ON signal of the SW and then delivers the working signal for a certain period. However the timer TB does not deliver the working signal while the timter TA is working. The signal of the timer TB is applied to one side of an OR circuit OR and also supplied to a monostable multivibrator MM. The circuit OR delivers the 2nd load controlling signal while the timer TB is delivering the signal and when the output of the MM is extinguished.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to controlling the operation of a switch function.

The purpose is to provide a switch and a control device that can selectively control two electrical loads or functions using a single switch.

There is a tendency for the number of electrical components to increase recently in automobiles, etc., and each electrical load has a switch installed, so -
It was difficult to secure enough space to install the switch, so the switch had to be made smaller, the switch could be operated in multiple directions, or it had to be installed outside the proper location.

However, an abnormal increase in the number of switches or miniaturization of the switches reduces operability, and increasing the number of switches leads to a decrease in visibility, and the switch becomes complicated. It was not necessarily a good idea as it lowered reliability due to C; and C;.

This invention uses a switch that is operated on and off, and when the unit operation from on to off exceeds a predetermined time, this is detected by the first output means and the first load or function is applied. When an operation is performed for a predetermined short period of time, the first output means C outputs the control signal; Means outputs the control signal to the second load or function, allowing one switch to control two functions that are related to each other, or two loads that are operated in sequence with each other.

Embodiments of the invention will be described below with reference to the drawings.

In the block diagram of FIG. 1, which shows the outline of the control, the signal from the operation switch is the first output means, which is a time-determined type. - and a time-returnable timer forming a component of the second output means. If the switch is turned on for a relatively long predetermined time, e.g. 0.5 seconds or more, the timer will operate until the switch is turned off after the predetermined time, and the output terminal R (low level The timer is designed to give a first load control signal expressed as .The timer operates immediately upon receiving the ON signal of the switch history, and thereafter outputs an operation signal for a certain period of time, for example, about 1 second. However, when the timer is in operation, the operation signal is not output.The signal of tie-rTh provides one C: low level signal of the OR circuit, and also serves as an input to the monostable! multi-chia circuit.

The monostable multiplier outputs an ORRr-high level signal for a predetermined short time C: after the start of the timer operation. OR circuit OR is a tie! - is outputting and on the condition that the output of the monostable multi-four disappears, it becomes a low level and the output terminal C becomes low so as to give the second load control signal represented by the low level. There is.

FIG. 2 shows details of the circuit shown in FIG. 1, and Φ is a positive power supply for control. The timer has a time constant for charging the capacitor using a kW resistor.

When the charging voltage C reaches a predetermined charging voltage, the transistor 〒r1 is operated, and the output terminal P1 connected to its collector is grounded (low) level 6, and the wrinkle output terminal C is connected. A charging voltage is applied to the transistor Tr1 via the resistive island. The resistor & is for discharging when the switch receiving the positive power supply ■ is turned off. The timer is a capacitor C.

It has a discharge time constant due to the resistor, and its output is at a high level C for a certain period of time after the switch is turned on and then turned off. The resistor & is a low resistance for protecting the switch contact from charging the capacitor when the switch is off, and is negligible with respect to the charging time C; for the capacitor.

The diodes ﾆ and ｈ are switched off during the off period C to prevent each capacitor from flowing back, causing false charges to flow back to each other.

Condensed? The false terminal is connected to the collector of the transistor Tr1' via the diode DI, and is connected to the collector of the transistor Tr1'.
1, its output is instantaneously 6; low level C; The diode DI prevents the potential at the output terminal from being grounded via the resistor R1 and the like when the transistor Tr1 is not in operation, and also prevents the monostable multi-circuit (to be described later) from malfunctioning. The terminal to the capacitor is also connected to the transistor Try via diode D4.
The collector of the low transistor is connected to the diode Dsr of the OR circuit and forms one input of the low circuit. After the transistor Tr*1t and J4 switch are turned on, - or Fi is C; after the transistor Tr*1t and J4 switch are turned on, the collector I is lowered after a predetermined time C; on the condition that the transistor Tr1 is off. Level C: This is normally set to high level C. The collector is further connected to one end of the capacitor ~ to configure a monostable multiplier. The other end of the capacitor has a charging time constant together with the resistor that receives the positive power supply ■, and the transistor D! When activated, it becomes a low level and immediately starts charging to provide a pace current to the transistor Tri, so that the mosquito transistor is activated after a predetermined period of time. Note that each of the temporary constants described above has a relationship of CIXRI>to×~>Cmu×Rmu. The collector of the transistor Trs receives the positive power supply Φ via the resistor R1, and the collector is connected to the diode D6 of the OR circuit OR.
The other input of the transistor Tri is set to low level when the transistor Tri is operating. The transistor Tr4 receives the signals from the diodes DseD4 via a resistor, and when both the diodes DI are at a low level, the transistor Tr4 outputs an inoperable signal. Then, when one of the diodes, in this case diode D6, becomes high level, it is activated, and if the positive power supply O is received through resistor R1, the collector of ζ is brought to low level. Transistor Trs
has its collector serving as the output terminal P2, its esetter is grounded, and its base is connected to the collector of the transistor Tr4. = To activate the connected load.

The operation of the above configuration I will be explained with reference to the time charts of FIGS. 3 and 4.

Figure 3 shows the case where the switch history is turned on and off in a short period of time. and descend. Capacitor tCA is hardly charged, point B is low level 1 & transistor Tr
1 is inoperative, and 0 point is at high level, so the output terminal P1 is at high level and the load is not activated. Point D is
Period 1 when the capacitor is at a predetermined high level; the transistor Tr! operation, the period becomes low level.

The first point is that after the capacitor reaches a low level, charging is stopped, and when the potential reaches a predetermined level, the F point becomes a low level. At the time when the level reaches the low level, the level at the point D is still at the low level, and the transistor Tr4 is in its own operation at this point, causing the level at the point G to be at the high level.

When the transistor Trs operates, the output terminal becomes low level, and the load operates. When point D becomes high level, it becomes inoperable.

Figure 4 shows a case where the switch history is turned on for a relatively long time C; point A is similarly charged and discharged, but during that time (the capacitor is charged and the potential of point B rises The transistor I Trl operates, and the points M and C become low levels. Therefore, the output terminal P1 becomes the image level and the load operates. At the same time, the transistor I Trl becomes inactive. Then, point D is at a high level, so the output terminal is at a high level, and the load is inactive.Then, when the switch is turned off, it discharges into the capacitor, and the transistor T
r1 becomes inoperable and the load becomes inoperable.

As described above, according to the present invention, the load L2 is operated for a short time by turning the switch on and off for a minute time, and the load L2 is not operated at that time, while the load L2 is not operated for a predetermined time I: For example, in the power window of a car, the load operates for a certain period of time, and the self-load does not operate.
By connecting the output terminal h t for one-touch operation and the output terminal for dual operation, it is possible to use and control depending on the operation of a single switch.
C: You can also use it in the same way: when you want to use it only once due to water splash, etc., and when you want to use it continuously. The actual value can be applied in various ways, such as by using various types of fine adjustment and coarse adjustment.
