12mm Metal push button switch momentary self locking latching brass stainless steel waterproof Car Auto Engine PC Power Start

DESCRIPTION

HC Electric metal push button switches are rugged and look real good while installing it! Simply drill a 16mm hole into any material, there's even a rubber gasket to keep water out of the enclosure. On the front of the button is a flat metal actuator, surrounded by a blue plastic LED ring. On the back there are 3 contacts for the button (common, normally-open and normally-closed) and 2 for the blue LED ring (+ and -). Connect 3 to 6V to the LED to have it light up nicely, there's a built in resistor! If you want to use this with a higher voltage, say 12V or 24V, simply add a 470 ohm resistor in series with the LED connection to keep the LED current at around 20mA. Also you can order 12V 24V 220V 380V push button directly.

This button has two options. One is momentary push button, when you press it the 'normally-open' contact shorts to the common contact. When you release it, the contacts open up again. The other is self locking latching type, when you press it the 'normally-open' contact shorts to the common contact. When you release it, the contacts stays the same state. Until you press it again, the contacts will be back to original state.
