Microswitch capacity issue

2011-12-15View Original

Thread Content

There is little attention paid to the rating of microswitches used in limit switches; typically, their rating is something like 10A 125/250VAC. I would like to ask the experts here: have you ever seen a switch with a rating of 10A 110VDC? ? ?

A standard microswitch with a current rating of at least 3A is sufficient for control purposes; however, it might not be adequate for directly controlling a pump – it’s better to use a contactor

10A 110VDC is really high

Reply to 3# backhamm1982: It’s a very high value indeed, and it’s also used in valve limit switches to transmit signals to control cabinets or DCS systems. As far as I understand, this direct current is generated by rectifiers, so such high currents shouldn’t be possible. Therefore, I think such capacity switches don’t exist, or there might be an issue with the design parameters; but I’m not sure. In case they do exist... I’m just checking to be sure, not to be laughed at. Thank you for your reply. . .
