I recently purchased an electronic hobby kit to build an Infrared Toggle Switch (Circuit Specialists, Kit 58) which I want to use to turn on/off a standard 100 watt incandescent light bulb. I have assembled the kit and it works perfectly. In the instructions it says: The maximum contact current is 1A. This on-board relay should be used to control an off-board relay or switch. It should not be used to switch high currents or high voltages directly. However, the rating on the relay says: 3A 120VAC 24VDC (Songle SRSZ-12VDC-SH). Also, my understanding is that a 100 watt bulb draws .83 amps (100/120).
I have two questions: 1) because the relay indicates the capacity to handle up to 3A and a light bulb draws considerably less (.83 amps) could I not use the relay directly? And 2) if I have to use an off-board relay or switch, can someone provide me detailed instructions on how to do this?
