A button switch, R1 is a resistor that limits the test input current, 4 is a current setting changeover switch that switches input current setting resistors R2 to R5, 5 and 5' are AC power input terminals, 6 is a power transformer, D3. D4 is a rectifier diode, Rs and C are smoothing resistors and capacitors, 7 is an electronic circuit and output relay configured to operate above the current setting value, and 8 is used for alarming or interrupting the operation of the relay. The contacts DI and D2 are overvoltage limiting diodes.

る。When conducting a test to check whether the relay operates without any abnormality in the conventional device having the circuit configuration as described above, by pressing the push button switch 3, the test current is applied from the terminals 5 and 5' through the power transformer 6. The current flows to the input circuit of the relay via the current limiting resistor R1, and if there is no abnormality, the output contact 8 will close, but if there is an abnormality, it will not close.
This allows confirmation of whether the relay is in operation or not.
上記した従来装置では継電器動作確認試験のための入力
電流を与えるために押ボタンスイッチ３を設けており、
しかもこのため配線ハンダ付は作業を必要とする。In the conventional device described above, a pushbutton switch 3 is provided to provide an input current for a relay operation confirmation test.
Moreover, for this reason, soldering the wiring requires work.
本考案は、上記押ボタンスイッチが不要となる構成の試
験機構を提供して上記問題を解消し信頼性の向上を図る
と共に、原価低減に寄与せんとするものである。The present invention aims to solve the above problems and improve reliability by providing a test mechanism that does not require the push button switch, and also contributes to cost reduction.
第２図は本考案による試験機構の一実施例を示す回路図

換用スイッチ４に試験入力電流をの入切を行なう機能を
持たせたものである。As shown in this figure, in the present invention, the push button switch 3 shown in Fig. 1 is not used, and instead, a current setting changeover switch 4 is provided with the function of turning on/off the test input current. It is something.
このように、本考案によれば、押ボタンスイッチが不用
となるので、このための部品代が不要になると共に配線
が簡略化され、原価低減させることができる。As described above, according to the present invention, since a push button switch is not required, the cost of parts for this becomes unnecessary, wiring is simplified, and the cost can be reduced.

押ボタンを不要としたが１、第３図に示すように、電流
整定に電力用継電器のタッププレート９を使用し、試験
のタップにタッププラグを挿入する構成としてもよい。In the example shown in Fig. 2, a changeover switch is used to eliminate the need for a push button, but as shown in Figs. 1 and 3, the tap plate 9 of the power relay is used to set the current, A configuration may also be adopted in which a tap plug is inserted.
ただ、このような構成であれば、タッププラグをねじ込
む途中において、接触が安定しないので、継電器の接点
が安定しない場合があるが、実用上は清算問題ない。However, with this configuration, the contact may not be stable while the tap plug is being screwed in, so the contacts of the relay may not be stable, but this is not a problem in practice.
