South El Monte, Calif. Electro-Mech Components, Inc. has released a compact single-station lighted pushbutton switch that features a bright bi-color LED light source with a Fresnel lens button for high visibility and installation into small spaces. Aimed at applications that require consistent and reliable operation, the Model SW44473 may used in avionics, instrumentation panels, power machine control, and medical instrumentation as well as status indicators in portable or headgear communications equipment and servers.
The SW44473 LED switch features SPST alternate action functionality (1 N.O. circuit) and a built-in resistor for operation at specific voltages. The unit is rated at 30 Vdc or 115 Vac, 2 amps resistive and 0.5 amps inductive. The operating pressure is 8 oz. (±4 oz) and the plunger travel is approximately 0.120 inches.
The LED switch measures 0.52 inches in diameter with a total switch depth of 1.52 inches, and requires 1.22 inches behind the mounting panel including solderable terminations. A clear 0.303-inch diameter lens cap protects the factory-installed bi-color LED. Extended switch function life is rated at 100,000 actuations minimum. Custom or special LED bulbs or lens colors, mountings, and termination methods (standard solder lug terminals) are available.
Unit prices range from $14.90 each in quantities of 100 to 249. Delivery is six to eight weeks.
Electro-Mech also offers three other series of lighted pushbutton switches for similar applications.
