Review on Twidec 10Pcs Mini Momentary Push Button Switch-1A 250V AC, 2 Pins SPST, Normal Open, Black Red PBS-110-XBKR by Dewitt Bhattacharya

update: after the previous check, the seller contacted and sent a second set of switches, they all have a smaller diameter knob, and the nut and washer are removable, the quality of workmanship is still good, review updated. OLD REVIEW: Good job, but the red button is larger in diameter than the nut and washer so they can't be removed. If you have a U-shaped mount, no problem, but if you have to put the button through the hole, it won't.
