12V 12mm Silver Momentary Push Button Switch 4Pin Power Symbol LED
Specification: Product name: Push Button Switch Material: stainless steel Color: Silver LED color: White / Red / Green / Blue Switch Rating: 2A 36V Hole size: 12mm Size: approx.Length: 21.3mm Width: 14mm Operation Type: Momentary type (push it-on, release it-off) LED Voltage: 12 V (When the voltage is higher than 12V, you need to add external resistor.)
Features: - Made of stainless steel material, strong and durable. - High-grade appearance and nice touch feeling. - Copper plating silver terminals for good conductive properties. - Momentary type, push it-on, release it-off. - Metal button head durable for longstanding press. - Adopt rubber ring and hexagonal nut fixed, anti dust and waterproof, which make it great for outdoors use.
I bought two of these push buttons. Despite it's mentioned in the specification that the LED works with 12V, No it doesn't. You need to add 1K current limiting resistor in order to use it. Here is the schematics I'm adding.
I advice using a serial resistor, to avoid burning the led.
Calculation is simple. If it's a blue led (± 3V - 20 mA) and you power it with 12V,
than Resistor = (12-3) / 0,02 = 450 Ω
Select 470 Ω
