Read the data sheet carefully. You have an Omron D3V series switch. Your model D3V-11G6M-1C25-K is only rated at 3 Amps, that is what the 11 is all about in the part number (11: 11 (3) A at 250 VAC). Read the data sheet and see how the actual switch part number is built. While only rated at 3 amps AC switches like this can handle a few hundred mA DC but that is as good as it gets and especially working an inductive load. Within a few operations the contacts will have arced enough and fuse themselves together all toasted. The max shown in the data sheet is 11 amps and again AC. Finally if we get into the data sheet ratings:
D3V-11 250 VAC 11 A 1.5 A 6 A 2 A
The 6A is the inductive rating and the 2A is the motor load.
Finally we see Minimum applicable load 160 mA at 5 VDC
Anyway, the bottom line is that switch won't work the way you want it to.
As to Omron? Look at their D4MC Series of switches. These are what I would have used or similar in my original circuit. When we start looking at motor loads like the one you have switching DC current using a switch just isn't good design practice. This is likely why todays automotive is loaded with relays. Hell, my truck and my wife's truck have no less that 3 relay panels.
