I have a H&F bandsaw. model number BS300
The switch that is on the machine was underwater during the floods and has never been that great since, as it hums when power is applied to the saw regardless of whether the saw is actually turned on or not.
I decided to get another switch for the saw and I ordered one on ebay from China. The switch on the saw is a KEDU KJD12 switch (http://www.ebay.com.au/itm/Draper-COMPLETE-SWITCH-PLATE-KJD12-POWER-TOOLS-ACCESSORIES-/321008620224?pt=UK_Hand_Tools_Equipment&hash=item4abd9ad2c0)
I ordered a similarly spec'd switch, a JUCHE JCZ3B (http://www.ebay.com.au/itm/350833680646?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649) that is only 1/4 the price.
I got the switch, but it doesn't seem to behave properly. The KJD12 has a label on the side saying to use inputs 1 and 3 for the 230V input and then output goes through 2 and 4. The pins are clearly labeled 1, 2, 3 and 4 on the rear of the switch. It only has 4 pins.
The JCZ3B says to use pins 1 and 3 for the inputs and pins 2 and 4 for the outputs. There is a diagram on the side of the switch explaining this.
This is where the problem starts. The rear of the switch has 5 pins. they are labelled 13, 14, 23, 24 and A1 respectively. I connected the inputs to pins 13 and 23 and connected the outputs to 14 and 24 leaving A1 unconnected.
The saw starts but fails to hold the switch in the on position, so unless I physically hold the switch on, the saw stops. Not an acceptable state of affairs.
Can anybody tell me what I am doing wrong? Is it that I should not have got a momentary switch? Should I have got one of these (http://www.ebay.com.au/itm/AC-380V-2KW-I-O-2-Positions-Start-up-Motor-Self-Locking-Electromagnetic-Switch-/190850629649?pt=AU_B_I_Electrical_Test_Equipment&hash=item2c6f958011) instead?305822305823
