This pre-soldered switch can serve as a replacement for a lot of momentary switches found in lights, and is also useful for use in many momentary driver conversions.
Available with and without LEDs pre-soldered. 0.8mm PCB thickness.
LEDs are OPTIONAL.
Connection Points / Bridge Points:
Because this switch was designed to be as versatile as possible, there are several different connection points and possible configurations.
- Switch Connections: SW+ & SW- GND (SW- is ground).
- LED Connections:
- If connecting directly to Batt+ or from an MCU output: LED+ & bridge "LED- GND BRIDG."
- If switching from a negative side (such as a MOSFET): LED- & LED+. Do not bridge anything.
LED Option:
Optionally, you may have two color or white LEDs pre-installed on the switch, which are often used as indicator lights.
Three SMD 0603 resistors will come included, but not installed (4.7K, 19.1K & 36K). You can try different resistor combinations depending on your input voltage and desired LED brightness. We recommend that you start with 36K---you can then swap or stack more resistors to increase the current from there. It is not recommended to go above a few mA of current to these small LEDs. The lower the total resistance value, the brighter the LEDs will be.
