The invention provides a switch device and power equipment, the switch device comprises a crank assembly, a connecting rod assembly and a contact assembly, and the crank assembly comprises a first crank, a second crank and a limiting structure. The first crank is used for receiving driving force and driving the second crank to move in the first direction. The second crank is used for driving the contact assembly to be switched on through the connecting rod assembly when moving in the first direction. And the second crank is used for receiving the driving force to move along a second direction, rotates along a second rotation direction relative to the first crank, and drives the contact assembly to open through the connecting rod assembly. The limiting structure is used for limiting rotation of the second crank in the first rotation direction relative to the first crank in the process of moving in the first direction. According to the invention, the limiting structure is arranged to limit the rotation of the s
