MOSFET is also a kind of switch, but its switching frequency can reach up to 5MHz, much faster than normal mechanical relay. There are two screw terminals on the board. One for outer power source and the other for device you want to control. Grove - MOSFET will pass the power from one end to another when closed.

Featuring the HF32FA-G relay, this board is built for people who want reliability but don't want to deal with the bulk of traditional relay modules. It’s compact, it’s clicky, and it’s significantly safer than sticking two bare wires together. (Seriously, don't do that.)\u003c\/p\u003e\n\u003ch3\u003eThe Nerdy Bits (Specs)\u003c\/h3\u003e\n\u003ctable class=\"p_2981_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd width=\"275\"\u003e\n\u003cp\u003e\u003cspan data-font-family=\"default\"\u003eParameter\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd width=\"326\"\u003e\n\u003cp\u003e\u003cspan data-font-family=\"default\"\u003eValue\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cp\u003e\u003cspan data-font-family=\"default\"\u003eRelay Pin\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd\u003e\n\u003cp\u003e\u003cspan data-font-family=\"default\"\u003eD1\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"275\"\u003e\n\u003cp\u003e\u003cspan data-font-family=\"default\"\u003eOperating Voltage\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd width=\"326\"\u003e\n\u003cp\u003e\u003cspan data-font-family=\"default\"\u003e5V\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"275\"\u003e\n\u003cp\u003e\u003cspan data-font-family=\"default\"\u003eOperating Current\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd width=\"326\"\u003e\n\u003cp\u003e\u003cspan data-font-family=\"default\"\u003e1A\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"275\"\u003e\n\u003cp\u003e\u003cspan data-font-family=\"default\"\u003eRelay Life\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd width=\"326\"\u003e\n\u003cp\u003e\u003cspan data-font-family=\"default\"\u003e100,000 Cycle\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"275\"\u003e\n\u003cp\u003e\u003cspan data-font-family=\"default\"\u003eMax Switching Voltage\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd width=\"326\"\u003e\n\u003cp\u003e\u003cspan data-font-family=\"default\"\u003e250VAC\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"275\"\u003e\n\u003cp\u003e\u003cspan data-font-family=\"default\"\u003eMax Switching Current\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd width=\"326\"\u003e\n\u003cp\u003e\u003cspan data-font-family=\"default\"\u003e10A\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"275\"\u003e\n\u003cp\u003e\u003cspan data-font-family=\"default\"\u003eElectrical endurance\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd width=\"326\"\u003e\n\u003cp\u003e\u003cspan data-font-family=\"default\"\u003e1.5x10^4 OPS (10A 250VAC, Resistive load, at 85°C, 1s on 9s off)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"275\"\u003e\n\u003cp\u003e\u003cspan data-font-family=\"default\"\u003eDimension\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd width=\"326\"\u003e\n\u003cp\u003e\u003cspan data-font-family=\"default\"\u003e21*42mm\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eHighlights\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSatisfying Haptics:\u003c\/strong\u003e It makes a clicking sound.
