The MonkMakes relay can be used to switch low voltage devices such as light bulbs, a motor, a small heating element or even a string of 12V LED lighting. The voltage needs to be kept under 16V, but the relay will automatically protect itself against too much current.
Solid-state relay up to 2 Amp Peak 1 Amp continuous AC/DC It also has an active LED indicator It has a resettable polyfuse to protect against over-current Great for Arduino and Raspberry Pi Suitable for low frequency PWM
