Easiest way to break circuit with bumper switch (24V, 5A)

So I've got this motor that takes 24V and up to 5A and have a bumper switch I need to cut off the power to this motor. Problem is the switch closes the circuit when depressed and inverters don't take that much voltage or current so I'd have to design a circuit to use one. I'd rather not have an extra board so is there an easy way around this?

Ok, change of plans. I can extend the switch's wires to reach the controller circuit so now I don't need to worry about the 5A. I'll test later to see if the controller circuit is still 24V (I sincerely hope not). I'm studying computer engineering rather than electrical so I don't know if any inherent resistances in transistors and inverters would have any effect on the controller circuit. Any help is appreciated, as always.

Oh and if this belongs in Highly Technical or some other forum, please move it. I just thought that this is technically hardware and I'd get more responses in this forum.

I can't even visualize what your trying to do... however I tend to get the feeling that you just need a relay. What does the inverter have to do with it? What are you trying to accomplish?

Yes, relay seems probable as a solution currently. Basically, this particular type of switch closes the circuit when it's pressed and I need it to be the other way around. So in the controller circuit, I need it to be the other way around, which is why I thought of an inverter.

If this involves switching something through a computer, there are for this purpose ready made devices that work through RS-232 (serial port).

AC or DC?

Solid state relays are your friend.

You can use TINY switches including reed (magnetic) MOSFETs, you name it. The "coil" draw on a solid state relay is TINY.

Has to be a specific type of switch and there aren't many options for it. It's DC and I'm looking into relays now.
