One sturdy push button switch for anywhere you need a quick easy to install small push button. Good vintage quality (most likely USA made) Terminals look to be silver plated. Very small but sturdy heavy duty switch! looks to fit approx .15" diameter round hole threaded portion approx .1 " Depth of switch body behind threaded portion approx .35 " (not incl terminals) diameter of switch body approx .23" button color looks to be dark maroon, almost brown surplus. Looks like most have had the terminals soldered or tinned, a few have not, but none look worn so not sure that they had much if any use. Guaranteed good!
